39 Laetitia (pronounced /lɨˈtiːʃiə/) is a large, bright main belt asteroid.
Laetitia was discovered by J. Chacornac on February 8, 1856 and named after Laetitia, a minor Roman goddess of gaiety.
Observations of an occultation on March 21, 1998 produced several chords indicating an ellipsoid of 219×142 km.[2]
