In relation to all of the above it should be noted again that it is believed that Jupiter and Saturn remain near their birthplace in the far reaches of our solar system. But it is widely interpreted that the new found giant gas worlds with such close orbits have migrated inwards towards their suns.

They’re common enough that it looks like they are a normal part of planetary formation. But they’re not so common that other solar systems like our own, where Earths co-exist with gas giants that move in wide, circular orbits like Jupiter’s, won't be found.
