Yeah, gaseous planets like Jupiter aren't too uncommon, it's just its distance from the Sun that is. As planets like those like to migrate to weeklong orbits for some reason, But because of Saturn (or maybe not, we don't know for sure) Jupiter never migrated that far into the Solar System.

Hard to say. There are many cool Exoplanets, if I had to put my finger on just one though it would probably be Kepler-62f a super-earth orbiting within the HZ of a K-type main sequence star. But Kepler-442b and Kepler-47c aren't too far behind
