125 Liberatrix is a Main belt asteroid. It has a fairly reflective surface and an M-type spectrum. Liberatrix is a member of an asteroid family having its own name. It was found by Prosper Henry on September 11, 1872. It was the first asteroid he found. He and his brother Paul Henry found a total of 14 asteroids. The asteroid's name is believed to mark the liberation of France at the collapse of the Second French Empire in 1870. There are so far two seen occultations by Liberatrix. The lightcurve of the asteroid has a big amplitude, indicating a stretched or non-spherical shape.
