1955 McMath
1955 McMath, provisional designation 1963 SR, is a stony asteroid in the asteroid belt, about 10 kilometers in diameter and a member of the Koronis family of asteroids. It was discovered at the U.S. Goethe Link Observatory near Brooklyn, Indiana by the Indiana Asteroid Program on September 22, 1963.〔
The bright S-type asteroid orbits the Sun at a distance of 2.7–3.0 AU once every 4 years and 10 months (1,762 days). The orbit lies in the ecliptic and is hardly eccentric. It has an exceptionally well determined rotation period of 5.6 hours.〔〔〔 While NEOWISE measured a high albedo of 0.32, the ''Light curve data base'' project assumes a more conservative figure of 0.24.〔
It was named after American solar astronomer Robert Raynolds McMath (1891–1962), a bridge engineer and businessman and an astronomer. He co-founded the McMath-Hulbert Observatory in Lake Angelus, Michigan, United States. This observatory was deeded to the University of Michigan in 1931, he served as its director from 1931 to 1961. He was an adviser to the National Science Foundation in its early years and he chaired the panel that advised NSF on the need for a national observatory. Kitt Peak National Observatory site was chosen for the McMath-Pierce Solar Telescope. Robert McMath served as the first president of Association of Universities for Research in Astronomy (AURA) from 1957 to 1958 and thereafter as chairman of the AURA board. The lunar crater ''McMath'' is also named in his and his father's honour.〔
