2629 Rudra, provisional designation 1980 RB1, is a sizable
rotation period 123 hours and likely an elongated shape.[3] It was named after Rudra from Hindu mythology.[1]
Orbit and classification
Rudra is a
semi-major axis of 1.74 AU). Its orbit has an eccentricity of 0.23 and an inclination of 23° with respect to the ecliptic.[2] The body's observation arc begins with its first observation in January 1954, more than 26 years prior to its official discovery observation. The precovery was taken at Palomar Observatory and published by the Digitized Sky Survey.[1] On 15 April 2023 and on 23 July 2179, the asteroid will pass about 0.08 AU (12,000,000 km; 7,400,000 mi) from Mars.[2]

Physical characteristics
In the
SMASS classification, Rudra is an uncommon, carbonaceous B-type asteroid.[2]
Rotation period
In September 2010, a rotational
U=2).[7] Observations by the Wide-field Infrared Survey Explorer (WISE) found a higher brightness amplitude of 0.87 and 0.95, respectively, which indicates that the body has a non-spherical, elongated shape.[3]
Diameter and albedo
According to the surveys carried out by the
albedo between 0.064 and 0.07,[6][9][10][11][13][14] with a recently published diameter of 5.25±0.53 kilometers and an albedo of 0.064.[5][a][b]
The Collaborative Asteroid Lightcurve Link assumes a standard albedo for a stony asteroid of 0.20 and consequently calculates a smaller diameter of 2.19 kilometers based on an absolute magnitude of 15.67.[3]
