Our solar system formed about 4.6 billion years ago. The four planets closest to the Sun Mercury, Venus, Earth, and Mars are called the terrestrial planets because they have solid, rocky surfaces. Two of the outer planets beyond the orbit of Mars Jupiter and Saturn are known as gas giants the more distant Uranus and Neptune are called ice giants.

Eight planets have been discovered in our solar system. Mercury, Venus, Earth, and Mars are the planets closest to the Sun. They are called the inner planets. The inner planets are made up mostly of rock. The outer planets are Jupiter, Saturn, Uranus, and Neptune. Jupiter, Saturn, Uranus, and Neptune are large balls of gases with rings around them.
Our solar system has eight planets, and five dwarf planets - all located in an outer spiral arm of the Milky Way galaxy called the Orion Arm.
The planetary system we call home is located in an outer spiral arm of the Milky Way galaxy. Our solar system consists of our star, the Sun, and everything bound to it by gravity - the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune dwarf planets such as Pluto dozens of moons and millions of asteroids, comets, and meteoroids. Beyond our own solar system, there
Planets In 2006, subsequent to several discoveries of several large outer Solar System objects beyond Pluto one of which was found to be even larger than Pluto it was decided that a planet should be defined as an object which a orbits the sun, and b is massive enough not only to coalesce itself into a nearly spherical shape, but also to gravitationally dominate its region of the solar
