Solar System
Solar System are made up of:-Planets -asteroids -Comets-Moons -dust and gas
Formation of Solar System
Formed from the collapse of a
giant molecular cloud of dust
and gas approximately
4.6 billion years ago.
Gas began to collapse
under the weight of its own gravity.
At the center of
this spinning cloud, a
small star began to
form.
The star in the center eventually ignited forming
our Sun, while the smaller clumps
became the planets, minor planets, moons,
comets, and asteroids.

The Sun contains around 99% of all the material in the Solar System.
75% hydrogen and 25% helium by mass
Sun converts hydrogen to helium in its core
Sun contains 98% of all material in the Solar System
The larger an object is, the more gravity it has.
Sun attracts all the other objects in the Solar System.
