580 Selene is aminor planet orbiting theSun in theasteroid belt. The nameSelene is that of an ancientGreekgoddess of theMoon.[3] The name may have been inspired by the asteroid's provisional designation1905 SE.
This body orbits the Sun nearly midway between the orbits ofMars andJupiter. The orbital eccentricity is slightly lower than that of Mars. Based on its light curve, Selene has an estimated rotation period of 0.3947±0.0004 days, or just under 9.5 hours.[4] During each rotation, theapparent magnitude varies by 0.27. The approximate diameter of this asteroid is 46 km.[5] (Some sources list a diameter of up to 56 km.) Thealbedo is about 7%, comparable to that of theEarth's Moon.
