November 25 – Discovery of Asteroid 128 Nemesis (1872)

Asteroid 128 Nemesis was discovered on November 25th 1872 by J C Watson. It’s a C-type asteroid, estimated to be about 188km in diameter, and is one of the slower rotators, with a day of 39 hours. 128 Nemesis is the largest member of the Nemesis (or nemesian) family of asteroids, of which at least 129 have been identified by the Sloan Digital Sky Survey.

Nemesis, as the name might have already suggested to you, was the Greek goddess of retribution. She is generally thought to have been the mother of Helen of Troy and her twin sister Clytemnestra, as well as the more astronomically famous twins Castor and Pollydeuces (a.k.a. Pollux). Obviously, having two sets of twins, while unusual, was nowhere near bizarre enough for the Greeks, so the story goes that Nemesis, attempting to avoid Zeus (as usual) took the form of a goose. Zeus then turned into a swan, resulting of course in an egg from which her children are born.

What were those guys on?
