146 Lucina is a main-belt asteroid that was discovered by Alphonse Borrelly on June 8, 1875. It was named after Lucina, the Roman goddess of childbirth. This asteroid is large, dark and has a carbonaceous composition. The spectra of the asteroid displays evidence of aqueous alteration.
This body is orbiting the Sun at a distance of with a low eccentricity of 0.07 and an orbital period of 4.48 years. The orbital plane is inclined at an angle of 13.1ð to the plane of the ecliptic. Photometric observations of this asteroid made during 1979 and 1981 gave a light curve with a period of 18.54 hours.
Two stellar occultations by Lucina have been observed so far, in 1982 and 1989. During the first event, a possible small satellite with an estimated 5.7 km diameter was detected at a distance of 1,600 km from 146 Lucina. A 1992 search using a CCD failed to discover a satellite larger than 0.6 km, although it may have been obscured by occultation mask. Further evidence for a satellite emerged in 2003, this time based on astrometric measurements.
