1823 Gliese, provisional designation 1951 RD, is a stony asteroid from the inner regions of the asteroid belt. It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory on 4 September 1951.[5]
The S-type asteroid is a member of the Flora family. It has a diameter of about 8 kilometers with a geometric albedo of 0.24, as calculated by the Light Curve Data Base project.[3] It orbits the Sun at a distance of 1.9–2.5 AU once every 3 years and 4 months (1,213 days). Measurements in 2014 provided a well-determined rotation period of 4.49 hours.[lower-alpha 1][4]
The asteroid was named in honor of German astronomer Wilhelm Gliese (1915–1993), who worked at the Astronomisches Rechen-Institut and is well known for compiling about 1,000 stars located within 25 parsecs of Earth into the Gliese Catalogue of Nearby Stars.[2]
