1772 Gagarin (
background asteroid from the central region of the asteroid belt, approximately 9 kilometers in diameter. It was discovered on 6 February 1968, by Russian astronomer Lyudmila Chernykh at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean Peninsula.[11] The asteroid was named after cosmonaut Yuri Gagarin.[2]
Orbit and classification
Gagarin orbits the Sun in the central main-belt at a distance of 2.3–2.8 AU once every 4.02 years (1,467 days). Its orbit has an eccentricity of 0.11 and an inclination of 6° with respect to the ecliptic.[1] Gagarin first observation is a precovery that was taken at Turku Observatory in 1940, extending the body's observation arc by 28 years prior to its official discovery observation.[11]
Physical characteristics
Gagarin has been characterized as a rare
PanSTARRS' photometric survey.[10]
Rotation period
In February 1984, a rotational
Diameter and albedo
According to the survey carried out by NASA's
albedo between 0.138 and 0.164,[4][5] The Collaborative Asteroid Lightcurve Link assumes a standard albedo of 0.20 and derives a diameter of 8.00 kilometers with an absolute magnitude of 12.85.[3]
