1202 Marina (provisional designation 1931 RL asteroid from the outermost regions of the asteroid belt , approximately 55 kilometers in diameter. It was discovered by Grigory Neujmin at the Simeiz Observatory in 1931, and later named in honor of Marina Lavrova–Berg, a scientific collaborator at Pulkovo Observatory , who died at an early age during WWII .[3]
Discovery
[ edit ]
Marina was discovered on 13 September 1931, by Soviet astronomer Grigory Neujmin at the Simeiz Observatory on the Crimean peninsula.[3] Karl Reinmuth at the Heidelberg Observatory on 15 September 1931.[2] Minor Planet Center only recognizes the first discoverer.[3]
The asteroid was first observed as A924 WG at Heidelberg Observatory in November 1924. The body's observation arc also begins at Heidelberg in January 1925, more than 6 years prior to its official discovery observation at Simeiz.[3]
Orbit and classification
[ edit ]
Marina is a non-family background asteroid of the Hilda group , located in the outermost region of the main-belt and in a 3:2 resonance with the giant planet Jupiter .[10] [4] AU semi-major axis of 4.00 AU ). Its orbit has an eccentricity of 0.17 and an inclination of 3° with respect to the ecliptic .[1]
Physical characteristics
[ edit ]
In the Tholen classification , Marina is a primitive P-type asteroid .[4]
Rotation period
[ edit ]
In the 1990s, a rotational lightcurve of Marina was obtained from a survey of Hildian asteroids by European astronomers. Lightcurve analysis gave a well-defined rotation period of 9.45 hours with a brightness variation of 0.29 magnitude (U=3 [7] Palomar Transient Factory in California gave a similar period of 9.571 hours and an amplitude of 0.09 (U=1 [8]
Diameter and albedo
[ edit ]
According to the surveys carried out by the Infrared Astronomical Satellite IRAS and the Japanese Akari satellite , Marina measures 54.93 and 63.76 kilometers in diameter and its surface has a low albedo of 0.0337 and 0.026, respectively.[5] [6]
The Collaborative Asteroid Lightcurve Link derives an albedo of 0.045 and a diameter of 55.07 kilometers based on an absolute magnitude of 10.28.[4]
Naming
[ edit ]
This minor planet was named after Marina Davydovna Lavrova–Berg (1898–1943), a scientific collaborator who worked at the Pulkovo Observatory near Saint Petersburg during 1931–1942.[2]
