129 Antigone is a large main belt asteroid. It is composed of almost pure nickel-iron. It and other similar asteroids probably originate from the core of a shattered Vesta-like planetesimal which had a differentiated interior.
It was discovered by C. H. F. Peters on February 5, 1873 and named after Antigone, the Theban princess in Greek mythology.
In 1979 a possible satellite of Antigone was suggested based on lightcurve data.[1] (http://www.johnstonsarchive.net/astro/asteroidmoonsq.html) A model constructed from lightcurve data shows Antigone itself to be quite regularly shaped. [2] (http://www.astro.helsinki.fi/~kaselain/thirty.pdf)
Since 1985, a total of three stellar occultations by Antigone have been observed.
