(230) Athamantis is an asteroid of the asteroid belt that was discovered on September 3, 1882 by Leo Anton Carl de Ball at the Bothkamp observatory near Kiel . De Ball had actually wanted to observe the asteroid (12) Victoria that night .
The celestial body was named after Athamantis (or Helle ), the daughter of Athamas, king of Thebes , from Greek mythology . Since Athamantis was very "bright" at the time, this could have inspired de Ball to give the name.
Athamantis moves 2.2353 ( perihelion ) to 2.5293 ( aphelion ) astronomical units around the Sun in 3.6771 years . The orbit is inclined 9.4344 ° to the ecliptic , the orbital eccentricity is 0.0617.
Athamantis has a diameter of 109 kilometers. The asteroid has a relatively bright, silicate-rich surface with an albedo of 0.171. It rotates around its own axis in around 23 hours and 59 minutes.
