3963 Paradzhanov
3963 Paradzhanov, provisional designation, 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. The asteroid was named after Soviet film director Sergei Parajanov in 1996.
Orbit and classification
Paradzhanov is a member of the Nysa family, the asteroid belt's largest asteroid family. The low-inclination family is located in the inner main-belt and named after 44 Nysa. It is better described as the "Nysa-Polana complex" because it consists of two 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. Paradzhanov has a relatively high albedo 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. Its orbit has an eccentricity of 0.20 and an inclination of 3° with respect to the ecliptic. The body's observation arc begins with its identification as at the discovering observatory in Nauchnyj in March 1979, almost 10 years after its official discovery observation.
