3787 Aivazovskij, provisional designation 1977 RG7, is a stony asteroid from the outer region of the asteroid belt, about 12 kilometers in diameter. It was discovered by Soviet–Russian astronomer Nikolai Chernykh at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula, on 11 September 1977.[8]
The S-type asteroid orbits the Sun at a distance of 2.5–3.2 AU once every 4 years and 10 months (1,760 days). Its orbit shows an eccentricity of 0.13 and is tilted by 12 degrees to the plane of the ecliptic. Three photometric light-curve analysis rendered a rotation period between 2.95 and 2.98 hours.[5][6][7]
Based on the survey carried out by the U.S. Wide-field Infrared Survey Explorer with its NEOWISE mission, the body has a high albedo of 0.33,[4] while the Collaborative Asteroid Lightcurve Link (CALL) assumes a somewhat more typical value of 0.20 for stony asteroids. As a consequence, CALL calculates the body to measure 15 kilometers, as the lower the reflectivity (albedo), the larger an asteroid's diameter for a given absolute brightness (absolute magnitude).[3]
The minor planet was named in honor of Russian painter of seascapes, Ivan Aivazovsky (1817–1900), who lived and worked in the Crimean city of Feodosia, and after which the minor planet 1048 Feodosia is named.[2][9]
