1944 Günter, provisional designation 1925 RA, is an asteroid from the inner regions of the asteroid belt, discovered by German astronomer Karl Reinmuth at Heidelberg Observatory on 14 September 1925.[3]

The asteroid orbits the Sun 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 is tilted by 5 degrees to the ecliptic plane. Little is known about the asteroids size, composition, albedo and rotation, despite having a well-observed orbit with the lowest possible uncertainty (i.e. a condition code of 0) and an observation arc that spans over a time period of almost a century.[1]

Karl Reinmuth named the asteroid after his son, Günter Reinmuth.[2]
