2227 Otto Struve, provisional designation 1955 RX, is an asteroid from the inner regions of the asteroid belt, approximately 4.7 kilometers in diameter. The asteroid was discovered on 13 September 1955, by the Indiana Asteroid Program at Goethe Link Observatory near Brooklyn, Indiana, United States.[5] It was named after Russian astronomer Otto Struve.[2]
Orbit and classification
The asteroid orbits the Sun in the
Johannesburg Observatory in 1935, extending the body's observation arc by 20 years prior to its official discovery observation.[5]
Physical characteristics
As of 2016, the asteroid's composition,
silicaceous rather than of a carbonaceous composition, with higheralbedos, typically around 0.20, the asteroid's diameter might be on the lower end of NASA's published conversion table, as the higher the reflectivity (albedo), the smaller the body's diameter at a constant intrinsic brightness (absolute magnitude).[4]
Naming
The minor planet is named in memory of Russian astronomer Otto Struve (1897–1963), discoverer of the two asteroids 991 McDonalda and 992 Swasey, and last of a remarkable dynasty of astronomers: the Struve family.
His great-grandfather, Wilhelm Struve (also see M.P.C. 8911/8912).[8]
