The sun is 72% Hydrogen and 26% Helium.

The sun has a diameter of 860,000 miles, which is 109 times larger than Earth.

The sun's core is 27,000,000℉ and the surface of the sun is slightly cooler and burns at a 10,000℉.

Our solar system is moving with an average velocity of 450,000 miles per hour (720,000 kilometers per hour). But even at this speed, it takes us about 230 million years to make one complete orbit around the Milky Way.

Its spin has an axial tilt of 7.25 degrees

During daytime temperatures can reach highs of 800°F, But at night, temperatures can dip as low as -290°F.

Mercury is the fastest planet, rotating around the Sun every 88 Earth days.

From the surface of Mercury, the Sun would appear more than three times larger as it does when looked at from Earth, and the sunlight would be as much as seven times brighter.

Mercury has no atmosphere to trap greenhouse gasses.

Mercury can be seen from Earth passing across the face of the Sun. This happens because Mercury’s orbit is inclined by 7 degrees to Earths orbit.

One day on Venus is more than one year on Earth.

Venus temperatures range from 86 to 158 Fahrenheit and the winds go up to 20 mph.

Venus rotates in the opposite direction to other planets. Most other planets rotate counter-clockwise on their axis, however Venus, like Uranus, rotates clockwise.

The atmosphere is a dense 96.5% carbon dioxide which traps heat and caused the greenhouse effect which evaporated any water sources billions of years ago.

One day on Venus would be 243 Earth days long

For one thing, your “day” would be 243 Earth days long

With an equatorial diameter of 7926 miles (12,760 kilometers), Earth is the biggest of the terrestrial planets and the fifth largest planet in our solar system.

The Earth was once believed to be the center of the universe. For 2000 years ancient astronomers believed that the Earth had bodies travelling in circular orbits around it.

The rotation of the Earth is gradually slowing down. The deceleration of the Earth’s rotation is very slow, approximately 17 milliseconds per hundred years.

Earth’s atmosphere is composed of 78% nitrogen, 21% oxygen.

Pieces of Mars have been found on Earth. It is believed that trace amounts of the Martian atmosphere were within meteorites that the planet ejected.

It takes Mars 687 Earth days to orbit the Sun

Mars has seasons like Earth, but they last twice as long

Mars once seems to have had intelligent life a long time ago

Mars is the only other planet besides Earth that has polar ice caps. The northern cap is called the Planum Boreum, with Planum Australe in the south. Water ice has also been found under the Martian ice caps.

Jupiter has the shortest day of the eight planets. The planet rotates very quickly, turning on its axis once every 9 hours and 55 minutes. This rapid rotation is also what causes the flattening effect of the planet, which is why it has an oval shape.

One orbit of the Sun takes Jupiter 11.86 Earth years.

Jupiter has at least 67 moons in satellite around the planet.

The largest of Jupiter’s moons, Ganymede is the largest moon in the solar system.

Jupiter lures larger asteroids and comets away from Earth and the other rock planets, Partly saving humankind

Saturn is one of five planets able to be seen with the naked eye

It takes Saturn 29.4 Earth years to orbit the Sun.

Saturn has 150 moons and smaller moonlets. All of these moons are frozen – the largest of which are Titan and Rhea. The moon Enceladus also appears to have an ocean hidden below its frozen surface.

Saturn is known as a gas giant, but scientists believe it has a solid rocky core surrounded by hydrogen and helium

Saturn’s atmosphere is composed of roughly 96% hydrogen and 4% helium
