text: Hmm-Im tempted to "geek" answer this question, using Greek and Latin roots, just for the heck of it-but more directly, its "as"teriod, not with 2 "s"s (I cant type it or it'll get starred out)-and Im not sure why objects falling from space would be called "hem".  If you used the same logic as the words, it would be called "proctoroids" or "anuroids".  "roid" means "like, but not quite", so you could call someone an "intelliroid" or "hunkaroid" or "foxaroid" and I suppose it would be an insult (yeah, I said "fox"-so I'm old, sue me)
