1944 Günter, provisional designation1925 RA, is anasteroid from the inner regions of theasteroid belt, approximately 5 kilometers in diameter.
It was discovered on 14 September 1925, by German astronomerKarl Reinmuth atHeidelberg Observatory in southern Germany, and named after the discoverer's son, Günter Reinmuth.[2][4]
Günter orbits the Sun in theinner main-belt at a distance of 1.7–2.8 AU once every 3 years and 4 months (1,224 days). Its orbit has aneccentricity of 0.24 and aninclination of 5° with respect to theecliptic.[1] As noprecoveries were taken and no prior identifications were made, the body'sobservation arc begins at Heidelberg, one night after its official discovery observation.[4]
According to the survey carried out by NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Günter measures 4.9 kilometers in diameter, and its surface has analbedo of 0.117.[3] As of 2017, its composition,rotation period and shape remain unknown.[1][5]
Thisminor planet was named by Karl Reinmuth after his son, Günter Reinmuth.[2] The officialnaming citation was published by theMinor Planet Center on 18 April 1977 (M.P.C. 4157).[6]
