Carl Alvar Wirtanen (November 11, 1910, Kenosha, Wisconsin – March 7, 1990 Santa Cruz, California) was an American astronomer and discoverer of comets and minor planets who worked at Lick Observatory.[2][3]
He discovered periodic comet 46P/Wirtanen, as well as eight asteroids, including notably the Apollo asteroid (29075) 1950 DA, which may have a non-negligible probability of impacting the Earth in the year 2880. He also discovered two other Apollo asteroids: 1685 Toro and 1863 Antinous. Based on the Shane–Wirtanen survey, the Shane Wirtanen Catalogue, a count of galaxies, was his major work published in 1954.[4]
Wirtanen was of Finnish ancestry.[2]
The asteroid 2044 Wirt, discovered by himself at Lick Observatory in 1950, was named in his honor in on 1 January 1981 (M.P.C. 5688). The name was proposed by his college Arnold Klemola.[3][5]
