4429 Chinmoy, provisional designation Template:Mp, is a Nysian asteroid from the inner regions of the asteroid belt, approximately Script error: No such module "convert". in diameter. It was discovered on 12 September 1978, by Soviet astronomer Nikolai Chernykh at the Crimean Astrophysical Observatory in Nauchnij, on the Crimean Peninsula.[1] The likely S-type asteroid was named after Indian spiritual leader Sri Chinmoy.[1]

Orbit and classification

Chinmoy is a member of the Nysa family (405Script error: No such module "Check for unknown parameters".),[2] one of the largest asteroid families and part of the Nysa–Polana complex with nearly 20 thousand identified members.[3]

It orbits the Sun in the inner main-belt at a distance of 1.9–2.9 AU once every 3 years and 8 months (1,341 days; semi-major axis of 2.38 AU). Its orbit has an eccentricity of 0.21 and an inclination of 1° with respect to the ecliptic.[4]

The body's observation arc begins with a precovery taken at Palomar Observatory in February 1954, more than 24 years prior to its official discovery observation at Nauchnij.[1]

Physical characteristics

Chinmoy has an absolute magnitude of 14.6.[4] While its spectral type has not been determined, it is likely a stony S-type asteroid based on its membership to the Nysa family and its albedo (see below).[4][2] 4429 Chinmoy appears to be in non-principal axis rotation ("tumbling") with P1= 44.99 ±0.05h main period and P2= 50.35 ±0.08h secondary period (Center for Solar System Studies Observatory, August 2022).[4]

Diameter and albedo

According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Chinmoy measures 3.498 kilometers in diameter and its surface has an albedo of 0.229.[5]

Naming

This minor planet was named after Indian spiritual leader Sri Chinmoy (1931–2007).[1] The official naming citation was published by the Minor Planet Center on 25 April 1994 (M.P.C. 23351Script error: No such module "Check for unknown parameters".).[6]
