I guess a lot of people could not describe what a galaxy is. Solar system - our sun and the planets that go around it. Galaxy - hundreds of billions of suns clustered in space. We call ours the Milky Way after the band of stars you can see on clear nights. Other galaxies - Andromeda is well visible from Earth, but there’s probably again hundreds of billions of them.
