The asteroid orbits the Sun at a distance of 3.0–3.3 AU once every 5 years and 7 months (2,027 days). Its orbit shows an eccentricity of 0.05 and is tilted by 6 degrees to the plane of the ecliptic.[1] According to the survey carried out by the Infrared Astronomical Satellite, IRAS, the asteroid's surface has an extremely low albedo of 0.02.[1] The body's spectral type remains unknown, as does its rotation period. By 2014, there were only 22 asteroids with an unknown rotation period for the low-numbered asteroids up to number 1000 (also see 398 Admete).
Any reference of this name to a person or occurrence is unknown.[2]
