1380 Volodia (prov. designation:1936 FM) is a carbonaceousbackground asteroid from the outer region of theasteroid belt. It was discovered on 16 March 1936, by French astronomerLouis Boyer at the North AfricanAlgiers Observatory in Algeria.[3] Five nights later,Volodia was independently discovered byEugène Delporte atUccle in Belgium.[2] The darkD-type asteroid has arotation period of 8 hours and measures approximately 22 kilometers (14 miles) in diameter.
ThisC-type asteroid orbits the Sun at a distance of 2.8–3.5 AU once every 5 years and 7 months (2,045 days). Its orbit has aneccentricity of 0.10 and aninclination of 10° with respect to theecliptic.[1]Volodia'sobservation arc begins with its official discovery at Johannesburg, as noprecoveries were taken, and no prior identifications were made.[3]
Thisminor planet is named for Russian Vladimir Vesselovsky (born 1936), who was born on the night of the asteroid's discovery. "Volodia" is the diminutive of "Vladimir".[2] In 1955, its naming citation was first published byPaul Herget inThe Names of the Minor Planets (H 125).[2]
In theSDSS-based taxonomy,Volodia is a darkD-type asteroid, which is common in the outer main-belt and among theJupiter trojan population.[10]
In April 2008, a fragmentarylight-curve ofVolodia was obtained fromphotometric observations by astronomer Eric Barbotin. Light-curve analysis gave a tentativerotation period of 8 hours with a change in brightness of 0.15magnitude (U=1+).[9]
According to the survey carried out by NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Volodia measures between 21.76 and 23.27 kilometers in diameter, and its surface has analbedo between 0.074 and 0.090.[6][7][8] TheCollaborative Asteroid Lightcurve Link assumes an albedo of 0.058 and calculates a diameter of 24.09 kilometers based on an absolute magnitude of 11.8.[11]
