Introduction to Our Solar-System

Our Solar-System consist of nine planets and the sun. These nine planets are called (nearest to sun to far side): Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto (eventhough now it's too small to be called a 'planet', therefore it's a 'dwarf planet').
Planets that are orbiting a star other than the sun are extrasolar planets. So far Astronomers and Scientists together have found 134 extrasolar planets. An exoplanet is another word for extrasolar.



You can see the structure of the solar-system clearly on the labelled diagram above, but you can't see the asteroid belt. It lies between Mars & Jupiter. Asteroids on Jupiter's orbit are Trojan Asteroids).
