Carl Alvar Wirtanen (November 11, 1910, Kenosha, Wisconsin – March 7, 1990 Santa Cruz, California) was an American astronomer who worked at Lick Observatory.
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. The Shane Wirtanen Catalogue, a count of galaxies, was his major work published in 1954.[1] He was of Finnish ancestry.[2]
