We just learned a little about our Solar System.

Let's learn about Orbit!

The earth orbits around the sun, which means that it spins around the sun kind of like the outside of a ferris wheel or merry go round.
It takes one year for the earth to do a full orbit around the sun.

The moon orbits around the earth, and we see a full moon about every 27 days, almost a whole month.
If there are two full moons in one month, that is called a blue moon.

The earth spins (rotates) and when it does a full spin around that takes one day.
