Are There Other Solar System Types of Planets?

When we look at other solar systems, we see something really weird. Most solar systems have a lot more planets very close to their star. Like between mercury and the sun, there's basically nothing. But in other solar systems, there are lots of planets packed in there. In particular, we find these things called hot jupiters, not hot because they're like, you know, big on instagram, or the really hervy hot because they're really close to the sun.
