1341 Edmée, provisional designation1935 BA, is a rare-type metallicasteroid from the central region of theasteroid belt, approximately 27 kilometers in diameter.
It was discovered on 27 January 1935, by Belgian astronomerEugène Joseph Delporte atUccle Observatory in Belgium, and later named after French astronomerÉdmée Chandon.[2][13]
Edmée orbits the Sun in themiddle main-belt at a distance of 2.5–3.0 AU once every 4 years and 6 months (1,658 days). Its orbit has aneccentricity of 0.08 and aninclination of 13° with respect to theecliptic.[1] In 1917 it was first identified asA917 DA atHeidelberg Observatory. The body'sobservation arc begins at Uccle, on the night following its official discovery observation in 1935.[13]
Edmée is classified as a rare XB-type in theTholen taxonomy, an intermediary between theX andB type asteroids.[1][3]
American astronomerRobert Stephens obtained several rotationallightcurves ofEdmée between 2004 and 2014. Best rated results include an observation taken at the Goat Mountain Research Observatory (G79) during the body's 2009-opposition, which gave arotation period of 23.745 hours with a brightness variation of 0.05magnitude (U=2+),[10] superseding an alternative period solution of 11.89 (U=2).[9]
BecauseEdmée's rotation is similar to that of Earth, photometric observations are challenging.[11][a] In 2013, a much shorter period was derived from a fragmentary lightcurve at thePalomar Transient Factory in California (U=1).[8]
According to the surveys carried out by the Infrared Astronomical SatelliteIRAS, the JapaneseAkari satellite, and NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Edmée measures between 23.86 and 27.49 kilometers in diameter, and its surface has analbedo between 0.137 and 0.182.[4][5][6][7] TheCollaborative Asteroid Lightcurve Link adopt the results from IRAS, that is, an albedo of 0.1371 and a diameter of 27.49 kilometers with anabsolute magnitude of 10.58.[3]
Thisminor planet was named in honour of French astronomer Édmée Chandon.[2] Naming citation was first mentioned inThe Names of the Minor Planets byPaul Herget in 1955 (H 122).[2]
