SOLAR SYSTEM PLANETS

Mercury is the innermost planet in the Solar System. It is also the smallest, and its orbit is the most eccentric (that is, the least perfectly circular) of the eight planets.

Venus is the second planet from the Sun, orbiting it every 224.7 Earth days.[11] The planet is named after the Roman goddess of love and beauty. After the Moon, it is the brightest natural object in the night sky.

Earth is the third planet from the Sun, and the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the Solar System's four terrestrial planets. It is sometimes referred to as the world, the Blue Planet.

Mars is the fourth planet from the Sun and the second smallest planet in the Solar System. Named after the Roman god of war, it is often described as the "Red Planet".

Jupiter is the fifth planet from the Sun and the largest planet in the Solar System.[13] It is a gas giant with mass one-thousandth that of the Sun but is two and a half times the mass of all the other planets in the Solar System combined. Jupiter is classified as a gas giant along with Saturn, Uranus and Neptune.

Saturn is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter.  Saturn is a gas giant with an average radius about nine times that of Earth. Saturn is just over 95 times more massive than Earth.

Uranus is the seventh planet from the Sun. It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System.  Uranus is similar in composition to Neptune, and both are of different chemical composition than the larger gas giants Jupiter and Saturn.

Neptune is the eighth and farthest planet from the Sun in the Solar System. It is the fourth-largest planet by diameter and the third-largest by mass. Neptune is 17 times the mass of Earth and is somewhat more massive than its near-twin Uranus, which is 15 times the mass of Earth but not as dense.

 Pluto is the second-most-massive known dwarf planet in the Solar System (after Eris) and the tenth-most-massive body observed directly orbiting the Sun.  Pluto is composed primarily of rock and ice and is relatively small, approximately one-sixth the mass of the Earth's Moon and one-third its volume.
