An alien is a stranger, sometimes coming from an extraterrestial body in space. From the thesaurus: A foriegner, non-citizen, outlander, outsider, traveler, traveller, au pair, deportee, exile, gringo, import, importee, metic, stranger, unknown, interloper, intruder, tresspasser, extraterrestrial, extraterrestrial being, or a hypothetical creature. The guy above my answer forgot to add grey. aliens are also called greys:)
