The four inner planets are: Mercury, Venus, Earth, and Mars.
Mercury is very hot and dry, because it is the closest planet to the Sun.
Venus is the second planet from the Sun and the hottest. It is the hottest,
because of its thick atmosphere that traps the Sun’s heat.
5. Earth is the only planet that can sustain life, because it has liquid water,
atmosphere, and mild temperatures.
6. Mars is the fourth planet from the Sun and has a reddish-orange rocky
surface. Mars also has two moons.

the only outer planet that is not made of gas and does not have rings.
