Science

The Sun is a star though? It's not one you should look at with your bare eyes though, since it is relatively close to Earth. It'll burn your eyeballs. Most other stars are many many light years (the distance that LIGHT travels in a year) away from Earth, so they look super tiny and don't make night time bright like the Sun does during day time. Fun fact, many of the stars you see in the night sky aren't actually stars, but entire galaxies! There's also a bunch of binary star systems as well as triple star systems (trinary? ternary?), so when stars orbit around each other, the brightness changes. (e.g. if Star A and B orbit each other, and B is brighter than A, then when they orbit each other, you periodically see either star A or the brighter star B and, at a distance, it looks like one star that is varying in brightness, a variable star!)
