Our Galaxy, The Milky Way, Is A Tiny Part Of The Observable Universe

If you hold up a grain of sand, the patch of sky it covers contains 10,000 galaxies.

There are at least one hundred billion galaxies in the observable universe.

This is our galaxy, the Milky Way Galaxy. It is just one of those 100 billion galaxies.

The Milky Way Galaxy contains about 100-400 billion stars. Our Sun is just one of those stars.
