3963 Paradzhanov, provisional designation 1969 TP2, is a Nysian asteroid from the inner regions of the asteroid belt, approximately 6 kilometers in diameter. It was discovered on 8 October 1969, by astronomer Lyudmila Chernykh at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula.[5] The asteroid was named after Soviet film director Sergei Parajanov (Sargis Paradzhanov) in 1996.[2]

Orbit and classification

Paradzhanov is a member of the

albedo-groups and at least three collisional families: Nysa, Polana, Eulalia, named after 142 Polana and 495 Eulalia. These are difficult to distinguish as they are dynamically overlapping with different but varying albedos.[6][7]: 23  Paradzhanov has a relatively high albedo (see below) which places it into the stony
Nysian subgroup of the "Nysa-Polana complex".

It orbits the Sun at a distance of 2.0–2.9 AU once every 3 years and 10 months (1,392 days). Its orbit has an eccentricity of 0.20 and an inclination of 3° with respect to the ecliptic.[1] The body's observation arc begins with its identification as 1979 HS3 at the discovering observatory in Nauchnyj in March 1979, almost 10 years after its official discovery observation.[5]

According to the survey carried out by the

albedo of 0.192.[4]
