The asteroid was named on March 1, 1981 after the American astronomer Nicholas Mayall (1906-1993), who from 1934 to 1960 at the Lick Observatory on nebulae , supernovae , the movement patterns in spiral galaxies , on the redshift and on the age, the formation and Origin and the size of the universe .
