The exoplanet Achilles
From the Names Desk at Language Log Plaza, a bulletin from the October 31 New Scientist, p. 6:
ALIEN worlds deserve more romantic names. So says Wladimir Lyra at the Max Planck Institute for Astronomy in Heidelberg, Germany, who has proposed mythological monikers for the known exoplanets.
The profusion of planets discovered around other stars in the past 15 years are known only by drab and hard to decipher strings of numbers and letters – at least officially. Instead, Lyra suggests that the 400 exoplanets found so far should be named after characters from Greek and Roman mythology, in the same way the planets in our own solar system were. For example, MOA-2007-BLG-400-Lb becomes "Achilles" (arxiv.org/abs/0910.3989).
Alas, Lyra's suggestions are unlikely to become official. The International Astronomical Union, which approves names for objects in our own solar system, considers it impractical to name exoplanets, given how many of them are likely to be discovered.
On beyond the dwarf planet Pluto and off to other worlds!
