Athamantis (minor planet designation: 230 Athamantis) is a fairly large main-belt asteroid that was discovered by the German-Austrian astronomer K. de Ball on September 3, 1882, in Bothkamp. It was his only asteroid discovery. The asteroid was named after Athamantis, daughter of Athamas the mythical Greek king of Orchomenus.
Photometric observations of this asteroid gave a light curve with a period of 23.99 hours and a brightness variation of more than 0.20 in magnitude.[4] It has the spectrum of an S-type asteroid. During 1991, the asteroid was observed occulting a star. The resulting chords provided a cross-section diameter estimate of 101.8 km.[5]
