The CNET article Interstellar comet Borisov looks ordinary, making Oumuamua even weirder says:
A paper published Monday in Nature Astronomy lays out the early data on Borisov, which is just the second-ever object seen visiting our solar system from beyond. While scientists will get a better look as the comet comes closer to Earth over the next several weeks, so far it looks to be the same color and size as most ordinary comets. Earlier research also revealed it's behaving in familiar ways with a tail containing some of the same toxic gases we expect from intrastellar comets.
Is the word intrastellar commonly used to refer to objects within our solar system by astronomers, or is it just the editors creative reversal of interstellar.
Along the same lines, would extrasolar be used by astronomers to refer to objects outside of our solar system?
