Solar System includes the Sun together with the eight planets and their moons, the dwarf planets (Eris, Pluto, and Ceres), the asteroids, comets and other celestial bodies that orbit the sun. Pluto, known as the 9th planet, it is no longer recognised as one of the planets in the solar system. The four planets closest to the sun, Mercury, Venus, Earth, and Mars, are called the terrestrial planets because they have solid rocky surfaces. The four large planets beyond the orbit of Mars, Jupiter, Saturn, Uranus, and Neptune, are called the gas giants. Solar comes from a Latin word SOL meaning sun. The solar system was formed about 4.6 billion years ago.
