Our Solar System Earth is part of our solar system,

which is made up of the sun and all of the countless objects that revolve around it.

At the center is the sun- a star, or ball of burning gases. 109 times wider than Earth.

Sun The sun creates a strong pull of

gravity that keeps all the planets revolving around it.

-Mercury, Venus, Earth, and Mars.-Closer to the Sun

Gas Giant planets- Gassy and less dense.-Jupiter, Saturn, Uranus, and Neptune. - Farther from the Sun

How is it like on different planets?

Mercury and Venus are scalding hot. Earth only planet that has liquid on

are all gaseous so they are inhabitable.
