4429 Chinmoy
From Wikipedia, the free encyclopedia
Chinmoy is a member of the Nysa family (405),[3] one of the largest asteroid families and part of the Nysa–Polana complex with nearly 20 thousand identified members.[5]
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.[2]
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.[2] 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).[2][3] 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).[2]
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.[4]
