But doesn't it have planets orbiting it since stars are sun's?
There's probably at least 2. Our current way to detect exoplanets is fucking laughable, though. We just look for a dip in brightness when the planet passes the sun. All it takes is the wrong angle and we would miss tons of objects in distant galxies or solar systems.
We can't even find the 9th planet in our solar system quite yet. They believe it circles the sun once every 20,000 years. It's very, very far. A 9th planet would explain some orbital abnormalities in one of the asteroid belts though.
A solar system is the planets gravitating around a star. A galaxy is millions or billions of solar systems held together by some type of gravitational pull. I think you mixed the two up
Wait though.. what are stars officially?
The hot shiny things in the sky. When I have kids were gonna watch a lot of these videos together: https://youtu.be/3mnSDifDSxQ
Pretty good for intro things about the universe with cute graphics, even though it's a little over simplified.
