Planets and dwarf planets of the Solar System. Compared with each other, the sizes are correct, but the distances are not
A simple video explanation of the Solar System

The Solar System is the Sun and all the objects in orbit around it. The Sun is orbited by planets, asteroids, comets and other things.


The Sun is a star. It contains 99.9 percent of the Solar System's mass.[1] This means that it has strong gravity. The other objects are pulled into orbit around the Sun. The sun is mostly made out of hydrogen and helium.


There are eight planets in the Solar System. From closest to farthest from the Sun, they are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The first four planets are called terrestrial planets. They are mostly made of rock and metal, and they are mostly solid. The last four planets are called gas giants. This is because they are large planets that are mostly made of gas. Even though they are made of gas, they have much more mass than the terrestrial planets.


The Solar System also contains other things. There are asteroids, mostly between Mars and Jupiter. Further out than Neptune, there is the Kuiper belt and the scattered disc. These areas have dwarf planets, including Pluto. There are thousands of very small objects in these areas. There are also comets, centaurs, and there is interplanetary dust.


Six of the planets and three of the dwarf planets are orbited by moons. Furthermore, planetary dust orbits the gas giants. There are many other systems like the Solar System in the universe. Each star has the potential to have a planetary system. There are more than 200 billion stars in the Milky Way galaxy.

The Earth takes just over 365 days, so the Earth’s year is 365 days. It takes this planet 11.9 of the Earth’s years to make its orbit round the Sun. • Although its orbit, and therefore its year, is so much longer than the Earth’s, its day is much shorter. The Earth turns on its own axis, turning away from the Sun and so giving us day and night, once every 24 hours. It spins round much faster, turning on its axis once every 9.84 hours!• This fast spinning gives rise to very strong weather patterns in the clouds which surround the planet and so its appearance changes rapidly.• It is the stormiest planet in the Solar System. There is a permanent, but ever-changing whirlpool of storms, known as Great Red Spot which can be seen using a telescope. • This is the first of the “gas giants”• The gas giants are entirely composed of dense layers of gas.• It is made of hydrogen, helium, methane and ammonia. The cloudy sphere has bright belts on it which change their shape.• It can be seen without a telescope and so was known in the ancient world, but it was not until the invention of telescopes that astronomers were able to see Jupiter’s moons.• There are 64 moons in total, four of which are large enough to be easily observed with a small telescope.• The first person to discover and observe its moons was Galileo (1564-1642). . mariagraziamagni11 https://padlet.com/mariagraziamagni11/rmp7lbamco96/wish/146880946 2017-01-12 18:26:22 UTC https://padlet.com/mariagraziamagni11/rmp7lbamco96/wish/146880946 • This is the sixth planet in the Solar system and, when seen through a telescope, by far the most beautiful.• The bright globe of this planet is surrounded by rings which may be composed of ice. Three of these rings are visible from the Earth using a telescope. Photographs sent back from the US Voyager spacecraft in the 1980s were able to identify further narrower rings “ringlets” in between the three main rings. The main rings are labelled A, B and C, with A the outermost ring. Recently more rings have been found.• It n is the last planet that can be seen without using a telescope or binoculars and the planet was known in the ancient world before telescopes were invented. The rings, however, can only be seen using a telescope.• The rings were first seen by Galileo in 1610 • It has at least 18 moons, satellites which orbit round the planet attracted to it by the planet’s gravity.• The largest of the moons, Titan, is the 2nd largest in the Solar system, after Jupiter’s moon, Ganymede. Titan is larger than the Earth and is the only moon in the Solar system which is known to have an atmosphere. The atmosphere consists of nitrogen and methane. • It itself is named, like all the planets, after a Roman God. Saturn was a rather mysterious God but it is believed that he was the God of sowing seed and of the harvest.It is the second largest planet in the Solar System, after the giant Jupiter.• Its mass is 95 times that of the Earth and it has a diameter of 75,098 miles, or 142,750 kilometres.• It is 886 million miles, or 1426 million kilometres, from the Sun. • It takes 29½ years to make one complete orbit of the Sun. The Earth takes one year • Like Jupiter, however, it spins much faster on its axis than the Earth. The Earth completes one rotation (turning) on its axis in 24 hours, turning away from the Sun and back again to give us night and day. It , although so much bigger, completes a full rotation in just over 10 hours.• This rapid spinning leads to hurricane-like storms far, far stronger than anything that is seen on the Earth. There is a constant whirlwind storm at its south pole which can be observed with the strongest telescopes.• The four largest outer planets, Jupiter, Saturn, Uranus and Neptune, are known as the “gas giants” since it is thought they are entirely made up of dense layers of gas. It is a great ball of hydrogen and helium • Its axis is tilted and as the planet orbits the Sun we get different views of the rings. Twice in every orbit only the edge of the outermost ring can be seen; even that can only be seen by using the strongest telescopes. Twice during the orbit we can see the fully opened rings.• The rings all orbit it at different speeds and have gaps between them. mariagraziamagni11 https://padlet.com/mariagraziamagni11/rmp7lbamco96/wish/146885494 2017-01-12 18:38:33 UTC https://padlet.com/mariagraziamagni11/rmp7lbamco96/wish/146885494 • This planet cannot be seen from the Earth without a telescope. • The seventh planet from the Sun, it was not known in ancient times, unlike the planets from Mercury to Saturn.• It was first seen by 1781 during a survey of the sky using a telescope • It were also discovered 2 of its moons with a larger telescope.• it has a total of 27 moons. • It is one of the “gas giants”, the four outer planets which are entirely composed of gas, Jupiter, Saturn, Uranus and Neptune. • Most of the centre of it is a frozen mass of ammonia and methane, which gives it the blue-green colour. The atmosphere also contains hydrogen and helium. • It orbits the Sun lying on its side and takes 84 years to complete one orbit. The Earth goes round the Sun in 365 days, one year.• Because it is lying on its side as it orbits the sun, for nearly a quarter of its orbit one pole of the planet is in complete darkness. • It takes 17.9 hours to turn once on its own axis, faster than the Earth, which takes 24 hours and gives us the change from day to night.• He was the ancient Greek God of the heavens whose sons were the Giants and Titans. • It is the smallest of the four “giants”, but is still several times larger than the Earth. It has a diameter of 29297 miles, or 47, 150 kilometres, compared to the Earth’s diameter of just under 8000 miles, or 12,760 kilometres. • It is 1782 million miles, or 2869 million kilometres from the Sun. mariagraziamagni11 https://padlet.com/mariagraziamagni11/rmp7lbamco96/wish/146885990 2017-01-12 18:39:55 UTC https://padlet.com/mariagraziamagni11/rmp7lbamco96/wish/146885990 • It is the only planet that has an atmosphere containing 21 percent oxygen.• It is the only planet that has liquid water on its surface.• It is the only planet in the solar system that has life.• It is the only inner planet (Mercury, Venus, Earth and Mars) to have one large satellite, the Moon. Mars has two very tiny moons. Mercury and Venus have none.• It is fragile. Its surface is split into plates (tectonic plates) which float on a rocky mantle – the layer between the surface of the earth, its crust, and its hot liquid core. The inside is active and earthquakes, volcanoes and mountain building takes place along the boundaries of the tectonic plates. • It is the third planet from the Sun and comes between the planet Venus and the planet Mars.• It takes 365¼ days to complete its orbit round the Sun. The Earth’s year is therefore 365 days long but the ¼ days are added up and every fourth year has one extra day, on the 29th of February. • The planets closer to the Sun, Mercury and Venus, have shorter years. The planets further away from the Sun have longer years; Pluto takes 249 of our years to make one orbit of the Sun. • As it orbits round the Sun it turns on its axis, rotating right round in 24 hours. The side that faces the Sun has daytime and the side that is turned away from the Sun has night-time. When it is daytime in Britain, it is night-time on the opposite side , in New Zealand.• It is 93 million miles, or 150 million kilometers from the Sun. • Its diameter, the distance round its middle at the Equator, is 7928 miles, or 12760 kilometers. It is not an exact sphere; the diameter going round the North and South Poles is slightly less than the diameter round the Equator. • It is larger than Mercury, Venus and Mars, the planets closest to it. On astronomy maps it often looks smaller than Venus because Venus is shown with a thick layer of sulphuric acid .• It differs from all the other planets because it has such a wide diversity of life and intelligent beings. This has only been possible because of its atmosphere which has protected it and allowed life to flourish. mariagraziamagni11 https://padlet.com/mariagraziamagni11/rmp7lbamco96/wish/146886333 2017-01-12 18:40:43 UTC https://padlet.com/mariagraziamagni11/rmp7lbamco96/wish/146886333 • The discovery of this planet as one of the most exciting discoveries in astronomy.• This planet cannot be seen without a large telescope and was first seen in 1846 from the observatory in Berlin. • It is the 8th planet from the Sun. • It is the third largest planet in the Solar System, much smaller than the real giants, Jupiter and Saturn, and only a little bigger than Uranus.• It has a diameter of 29,297 miles, or 47,150 kilometres. The Earth has a diameter of 7928 miles (12,760 kilometres). • This is one of the four “gas giants”. Like Jupiter, Saturn and Uranus, it is composed only of gas. It is a great ball of hydrogen and helium. • Like all the other planets in the Solar System, it moves in an orbit round the Sun at the centre of the system. It takes it 165 of our Earth years to orbit the Sun. The Earth orbits the Sun in 365 days, one year.• In 2011 this planet completed the first orbit of the Sun since its discovery 165 years before in 1846. • The Earth turns right round on its own axis in 24 hours, giving us the change from day, when we face the Sun, to night, when our part of the Earth turns away from the Sun. this planet spins slightly faster on its axis, taking just over 19 hours to turn right round.• This planet is 2793 million miles (4495 million kilometres) from the Sun, and 2700 million miles from the Earth. • We now know that it has 13 moons in total. . mariagraziamagni11 https://padlet.com/mariagraziamagni11/rmp7lbamco96/wish/146886556 2017-01-12 18:41:18 UTC https://padlet.com/mariagraziamagni11/rmp7lbamco96/wish/146886556 • The Red Planet is the fourth planet from the sun (Earth is the third). In a lot of ways, it looks a lot like our home, though instead of blue oceans and green land, it is home to an ever present red tint. This is due to a mineral called iron oxide that is very common on the planet’s surface. However, when you look past the surface differences, these two planets are similar in a lot of ways.• Polar Ice Caps – it has both North and South polar ice caps, much like Earth. Also like Earth, both ice caps are made mostly of frozen water. With so much water frozen in the ice caps some scientists think that life could have once existed there. • Length of a Year – it is not much farther from the Sun than Earth. As a result, a typical year is 687 days. • Length of a Day – While a year might be almost twice as long as a year on Earth, the length of a day there is almost identical. A day is 24 hours and 39 minutes long, less than an hour longer than a day on Earth. • Seasons – it has seasons like Earth too. These seasons are much longer than Earth seasons because it is so much farther from the sun. And don’t get your swim suits out just yet – the average high during a summer day is -5 degrees C – not exactly beach weather. o This planet and Earth are similar in so many ways that it’s almost hard to believe we haven’t found anything alive there. But, don’t forget that there are many differences too. • It is covered by craters from objects like asteroids and meteorites hitting the planet. Today, 43,000 such craters have been found and that only includes the large ones! • It doesn’t have a protective layer of atmosphere like Earth, so it cannot store heat from the sun. As a result, the temperature on regularly drops to - 82 degrees C in the winter and only rises to - 5 degrees C in the summer. mariagraziamagni11 https://padlet.com/mariagraziamagni11/rmp7lbamco96/wish/146886829 2017-01-12 18:42:00 UTC https://padlet.com/mariagraziamagni11/rmp7lbamco96/wish/146886829 • It is the brightest planet in the Solar System and can be seen even in daylight if you know where to look. When it is west of the Sun, it rises before the Sun in the morning and is known as the Morning Star. When it is east of the Sun, it shines in the evening just after sunset and it is known as the Evening Star. • It orbits round the sun in 225 days. The Earth takes 365 days to complete an orbit of the sun. So a year on it only lasts for 225 days! • It is the 2nd planet from the sun. The closest planet to the sun is Mercury. • The planets in the Solar system are given the names of Roman Gods or their attendants. It is called after the Roman Goddess of love and beauty. • It is the planet which is closest to the Earth and is a little smaller than the Earth. The circumference of the Earth (the distance right round the middle of the Earth at the equator) is 12,760 kilometres, or 7926 miles. The circumference is 12,103 kilometres, or 7520 miles. • It has no moons. • It is 67 million miles, or 108 million kilometres, from the Sun. • It is covered by clouds of water vapour and sulphuric acid and the surface cannot be seen with an ordinary astronomy telescope. • It is the hottest planet in the Solar System, even hotter than Mercury, which is closer to the Sun. The temperature on the surface is about 460° Celsius. • It has continents, mountains and craters. There is no life at all on it and life could never be supported there because of the extreme heat and the atmosphere. mariagraziamagni11 https://padlet.com/mariagraziamagni11/rmp7lbamco96/wish/146887145 2017-01-12 18:42:46 UTC https://padlet.com/mariagraziamagni11/rmp7lbamco96/wish/146887145 • It is the planet closest to the Sun. It is not, however, very close, since it is 36 million miles, or 58 million kilometres away from the Sun! • Like all the other planets it orbits round the Sun, but its orbit of the Sun lasts for only 88 days. The Earth’s orbit lasts for 365 days . • Because it goes round the Sun so quickly, the planet was called after the messenger of the Roman Gods. The messenger Hermes as the Greeks knew him, is usually shown as having wings on his helmet or on his sandals. • When it orbits the Sun, it travels 36 million miles, or 58 million kilometres in the 88 days of the orbit. It moves at a speed of 48 kilometres a second, or 107,372 miles an hour! • Unlike the Earth and most other planets it only turns very slowly on its axis, taking 59 days to complete the turn from day to night. • It has no atmosphere around it to protect it from the Sun or to retain any heat when it rotates on its axis. • It is quite a small planet. Its diameter, the distance right round its middle, is only 3100 miles or 4990 kilometres. The diameter of the Earth is 7926 miles or 12,760 kilometres. • It has no moons. Moons are satellites that travel with a planet as it orbits the sun. The earth has one moon, Mars has two very small ones, Jupiter, the giant of the planets, has 16! • The surface is covered with craters and completely dry. There is no possibility of life on Mercury.• It is one of five planets that can be seen without using a telescope, together with Venus, Mars, Jupiter and Saturn. • mariagraziamagni11 https://padlet.com/mariagraziamagni11/rmp7lbamco96/wish/146887291 2017-01-12 18:43:12 UTC https://padlet.com/mariagraziamagni11/rmp7lbamco96/wish/146887291 mariagraziamagni11 https://padlet.com/mariagraziamagni11/rmp7lbamco96/wish/148282178 2017-01-20 06:50:59 UTC https://padlet.com/mariagraziamagni11/rmp7lbamco96/wish/148282178
