The Planets in our Solar System

There are eight planets in the solar system and they all go around the Sun.
Our planet is called Earth and it goes around the Sun every 365 days. That is
one year! Earth also has a moon. We can live on Earth because there is air and
water here. Most planets and moons do not have these. . . . .
The nearest planets to the Sun are called Mercury
and Venus, then we have Earth. Some planets are very
far from the Sun. The furthest are called Uranus and
Neptune.

The biggest planet is called Jupiter. It is 11 times larger
than Earth and has more than 90 moons! Saturn is
amazing, too. This planet has 146 moons and a big ring
around it!
