120 LACHESIS

'120 Lachesis' is a very large and very dark main belt asteroid. As a primitive C-type asteroid it is likely composed of carbonates. It was discovered by Alphonse Borrelly on April 10, 1872 and named after one of the Moirae, or Fates, in Greek mythology. The only observed Lachesean occultation occurred in 1999 and was recorded in the south-western United States.
