Prolific asteroid hunter Alphonse Borrelly discovered main belt asteroid 146 Lucina on June 8th, 1875. It was the fifth of his 18 asteroids, and is a dark, carbonacous asteroid, and fairly large, at around 131 to 132 km across.
The name is slightly ambiguous. Lucina is the name given to the Roman goddess of childbirth, but there are two of them. While it is usually an epithet given to the goddess Juno, it can also refer to Diana, as both of them were involved in the birthing business.
In 1982, observations of a stellar occultation by Lucina made at the Meudon Observatory in France and reported in the journal Icarus (vol 61, issue 2) recorded a secondary event, possibly caused by a small satellite. This satellite was estimated to have a diameter of about 5.7 km, and to be about 1600 km from the asteroid.
In 2003, the case for a satellite was strengthened by observations of the orbital motion of Lucina, published in the proceedings of the 34th Annual Lunar and Planetary Science Conference by Jean-Baptiste Kikwaya and others from the Vatican State Observatory. It’s not absolute proof, but it’s looking likely that 146 Lucina may not be alone.
