(5422) Hodgkin is an asteroid of the main outer belt , which was discovered by the Soviet astronomer Lyudmila Georgievna Karachkina on December 23, 1982 at the Crimean Observatory in Nautschnyj ( IAU code 095). There had been several sightings of the asteroid before: on December 4, 1956 (1956 XS) at the Goethe Link Observatory in Indiana , on September 15, 1966 (1966 RK) at the Crimean Observatory in Nautschnyj and on September 16, 1976 ( 1976 RH 10 ) at the Felix Aguilar Observatory in Argentina .
According to the SMASS classification ( Small Main-Belt Asteroid Spectroscopic Survey ), a spectroscopic study by Gianluca Masi , Sergio Foglia and Richard P. Binzel at (5422) Hodgkin assumed a dark surface, so it could, roughly speaking, be trade a C asteroid .
The asteroid was on 1 September 1993 by Dorothy Hodgkin named, a British biochemist who for their analysis of the structure of vitamin B12 with X-rays the 1964 Nobel Prize in Chemistry was awarded.
