Scientists know many things about our solar system. It consists of the Sun and eight planets. The eight planets in the Solar System from closest to farthest from the Sun are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. It includes: the satellites of the planets; numerous comets, asteroids, and meteoroids; and the interplanetary medium. They know how old Sun is. The Sun is more than 4½ billion years old. The sun is mostly made out of hydrogen and helium. They know the Sun’s size. The Sun is the Solar System's star and by far its most massive component. The Sun may seem small, but that is because it is so far away. It is about 93 million miles (150 million kilometers) away from the Earth. The Sun is so large that the diameter of the Sun is 109 times the Earth‟s diameter. The Sun also weighs as much as 333,000 Earths. The Sun is the centre of our Solar System. Besides the Sun, the Solar System is made up of the planets, moons, asteroid belt, comets, meteors, and other objects. There are asteroids, mostly between Mars and Jupiter. Further out than Neptune, there is the Kuiper belt which has dwarf planets, including Pluto. There are thousands of very small objects in these areas. There are also comets, centaurs, and there is interplanetary dust. Six of the planets and three of the dwarf planets are orbited by moons. Furthermore, planetary dust orbits the gas giants. Many other systems like the Solar System have been found. Each of the billions of stars in the Milky Way galaxy might have a planetary system. Astronomers are now hunting for another planet in our solar system, a true ninth planet and it has been given the name as Planet Nine.
