      Well, there’s nothing especially special about our star (the sun): it’s just a yellow dwarf that’s very common in our galaxy. And a lot of stars that we’ve found have their own planetary system too (exoplanets), so that’s not uncommon either. Really the only super-special thing about our solar system is us: life! But even with all the billions of solar systems that must be out there, there won’t ever be one exactly like ours. Maybe some similar with some Earth-like planets, but our exact solar system is unique.

      our universe contains about 100 trillion galaxies , and each galaxy has roughly 50–200billion stars. Not all stars have planets but there is still going to be a lot of solar systems out there! The problem is finding out how similar they are to our solar system, but that’s because everything is so far away!
