GalaxyA system of stars mixed with gas and
dust.We are part of the Milky Way Galaxy,
which is a spiral galaxy.The next closest galaxy is called
Andromeda.
There are approximately 200 billion stars in our galaxy.

Moon
A naturally occurring satellite orbiting around a planet
Some planets have more than 1 moon

StarA massive ball of
luminous gas that are held together by their own gravity
A star creates its own light
The life cycle of a star is determined by its mass.
