Although Pluto-Charon is the only recognized binary planet in the solar system, there are binary asteroids and binary Kuiper Belt Objects. Of course, there are also many binary stars in the galaxy as well. New Horizons is expected to be the first mission to visit any kind of binary object.
The barycenter of the earth-moon system lies within the radius of the earth-- so it’s not a double planet.
This. If the spokeswoman had just said, “If you’ve ever tried to imagine what vomit looks like in shades of different colors, well here you go!” instead of comparing these paint smocks to heavenly bodies, we could have avoided this whole embarrassing conversation.
I actually have had people present a limestone concretion to me as a meteorite, as well as a terrestrial rock ‘because God told them it was from Mars!’ There does seem to be some confusion about what a meteorite is, although I don’t know what questions you ran into.

A fussy patron of the paranormal, Mizrahi chooses his psychics as carefully as his fabrics. “There’s my astrologer, Maria Napoli, who I’ve been seeing since I was eighteen. I go to her every six months for a checkup, like you would a doctor.” But since getting an appointment with Napoli is as difficult as getting into the Oscars, Mizrahi also recommends Tony LeRoy. “I see him for tarot readings two or three times a year. He’s a real optimist.”
AHA! but since EITHER the earth OR the moon would dynamically dominate the 1 AU orbit if it were here by itself, and since in reality BOTH such planetary bodies ARE here together in the same orbit, therefore it IS a double planet!
my favorite definition (barycenter), which I can cling to because I’m not an astronomer, and enjoy being pedantically difficult, has the interesting side effect of making Jupiter a double “star” with the “sun”. Yeah. That’s the kind of contradiction I can get behind, baby!
