I was interviewing an astronomer for a story about planets outside our solar system, extrasolar planets. Exoplanets have names like Kepler-11 e, or HD 106906 b, or HAT-P-54b. (Googling those names will get you some satisfyingly weird planets and in fact, most exoplanets are satisfyingly weird. I mean, 51 Peg b is 150 times more massive than Earth and is so close to its star, its year is four days.) Anyway, I found I needed to ask the astronomer whether he had trouble keeping all those names straight. “Sometimes I do,” he said, “not always.”
“Shouldn’t those exoplanets have real names?” I said.
“There’s a fuddy-duddy International Astronomical Union that gets worked up and forms committees to name things,” he said.
And well they might. Left to their own devices, astronomers just name things up one side and down the other: 51 Peg b is also called TYC 1717-02193-1 b, IRAS 22550+2030 b, BD+19 5036 b, HIP 113357 b, HR 8729 b, GJ 882 b, HD 217014 b, 2MASS J22572795+2046077 b, and SAO 90896 b.
Wouldn’t it be easier if they just called it, say, Lucille? When we care about something, don’t we name it? Continue reading →
