Solar System
The Solar System consists of the Sun and its planetary system of 8 planets ( not 9 , as Pluto is nowadays not considered as a planet ) ., their moons and other non - stellar objects. It is believed that solar system is formed with the gravitational collapse of large molecular cloud.
The vast majority of the system is in Sun , and the remaining ( most of it ) is in planet Jupiter. The 4 smaller inner planets are --------
1 . Mercury
2 . Venus
3 . Earth
4 . Mars
These are also called as terrestrial planets . They are primarily composed of rock and metal .
The remaining 4 planets are ----------
5 . Jupiter
6 . Saturn
7 . Uranus
8 . Neptune
These are called gas giants , Jupiter and Saturn are mainly consisted of gases like hydrogen and Helium where as Uranus and Neptune are composed of substances of relatively high melting points , and are referred as ice giants .
The asteroid belt lies between planets Mars and Jupiter . Sometimes these objects are also referred as dwarf planets .
