It is part of the so-called outer planets, and within these, it is one of the frozen giants, and it is the first that was discovered thanks to mathematical predictions. Its name was placed in honor of the Roman god of the sea - Neptune - and it is the fourth planet in diameter and the third largest in mass. Its mass is seventeen times that of Earth and slightly greater than that of its "twin" planet Uranus, which has fifteen Earth masses and is not as dense. On average, Neptune orbits the Sun at a distance of 30.1 ua. Its astronomical symbol is ♆, a stylized version of the trident of the god Neptune.

the third largest, and the fourth most massive. It is named in honor of the Greek divinity of the sky Uranus, the father of Cronus and the grandfather of Zeus.Although it is detectable with the naked eye in the night sky, it was not classified as a planet by ancient astronomers due to its low luminosity and the slowness of its orbit.13 William Herschel announced his discovery on March 13, 1781, expanding the then-known frontiers of the solar system, for the first time in modern history. Uranus is also the first plane​discovered by means of a telescope.

Saturn is the sixth planet in the solar system counting from the Sun, the second in size and mass after Jupiter, and the only one with a ring system visible from Earth. Its name comes from the Roman god Saturn. It is part of the so-called outer or gaseous planets. The most characteristic aspect of Saturn is its bright rings. Before the invention of the telescope, Saturn was the most distant of the known planets and, to the naked eye, it did not appear bright or interesting. The first to observe the rings was Galileo in 1610,1 but the low inclination of the rings and the low resolution of his telescope made him think at first that they were large moons. Christiaan Huygens, with better means of observation, was able in 1659 to clearly observe the rings. James Clerk Maxwell, in 1859, mathematically demonstrated that the rings could not be a single solid object but must be the grouping of millions of smaller particles. The particles that make up Saturn's rings rotate at a speed of 48,000 km / h, 15 times faster than a bullet.

Jupiter is the planet with the highest mass in the solar system: it is about 2.48 times the sum of the masses of all other planets together. Despite this, it is not the most massive planet known: more than a hundred extrasolar planets that have been discovered have masses similar to or greater than that of Jupiter.7 8 Jupiter also has the fastest rotational speed in the world. the planets of the solar system: it rotates in just under ten hours on its axis. This speed of rotation is deduced from measurements of the planet's magnetic field. The atmosphere is divided into regions with strong zonal winds with rotation periods ranging from 9:50 AM in the equatorial zone to 9:55 AM in the rest of the planet.

Mars is one of the planets superior to Earth, since its orbit never crosses that of the Earth around the Sun. Its phases (illuminated portion seen from Earth) are poorly defined, a fact that is easy to demonstrate geometrically. Considering the Sun-Earth-Mars triangle, the phase angle is that formed by the Sun and the Earth seen from Mars; this reaches its maximum value in the quadratures when the STM triangle is right on Earth. For Mars, this phase angle is never greater than 42 °, and its gibbous disk appearance is similar to that of the Moon 3.5 days before or after the full Moon. This phase, visible with an amateur telescope, could not be seen by Galileo, who only assumed its existence.24

It was formed approximately 4.55 billion years ago and life emerged about a billion years later.18 It is home to millions of species, including humans, and is currently the only astronomical body where life is known to exist.19 The The atmosphere and other abiotic conditions have been significantly altered by the planet's biosphere, favoring the proliferation of aerobic organisms, as well as the formation of an ozone layer that, together with the Earth's magnetic field, blocks harmful solar radiation, thus allowing life on the planet. Earth.20 Earth's physical properties, geological history, and its orbit have allowed life to continue to exist. It is estimated that the planet will continue to be able to support life for another 5000 million years, since according to current forecasts, after that time the increasing luminosity of the Sun will end up causing the extinction of the biosphere.

acks natural satellites. It receives its name in honor of Venus, the Roman goddess of love (gr. Aphrodite). It is a rocky and terrestrial planet, often called Earth's sister planet, since both are similar in size, mass and composition, although totally different in terms of thermal and atmospheric issues (the average temperature of Venus is 463.85 ° C). Its orbit is an ellipse with an eccentricity of less than 1%, forming the most circular orbit of all the planets; it hardly exceeds that of Neptune. Its atmospheric pressure is 90 times higher than the earth's pressure; It is, therefore, the highest atmospheric pressure of all the rocky planets in the solar system. It is white / yellowish in color due to its atmosphere composed mainly of carbon dioxide (CO2), hydrogen sulfide (H2S) and nitrogen (N2).

Mercury is the planet with the most craters in the Solar System. This is due to the numerous encounters with comets and asteroids. Most of these geological events are named after famous artists and writers.it is the planet of the solar system closest to the Sun and the smallest. It is part of the so-called inner or terrestrial planets and lacks natural satellites like Venus. Very little was known about its surface until the Mariner 10 planetary probe was sent and observations were made with radar and radio telescopes. It was later studied by NASA's MESSENGER probe and currently the European Space Agency (ESA) spacecraft called BepiColombo, launched in October 2018, is in flight to Mercury where it will arrive in 2025 and is expected to provide new knowledge about the origin and composition of the planet, as well as its geology and magnetic field.
