146 Lucina is a main belt asteroid. It is large, dark and has a carbonaceous composition.
It was discovered by Alphonse Borrelly on June 8, 1875 and named after Lucina, the Roman goddess of childbirth.
Two stellar occultations by Lucina have been observed so far, in 1982 and 1989. During the first event, a possible small satellite (6 km in diametre) was detected.
Further evidence for a satellite emerged in 2003, this time based on astrometric measurements [1] (http://www.johnstonsarchive.net/astro/asteroidmoonsq.html).
