1567 Alikoski, provisional designation 1941 HN, is a large, carbonaceous asteroid from the outer region of the asteroid belt, about 68 kilometers in diameter. It was discovered by Finnish astronomer Yrjö Väisälä at Turku Observatory, southwest Finland, on 22 April 1941.[8]
The dark C-type asteroid is also classified as a subtype of the very rare P-type asteroids in the Tholen taxonomic scheme. It orbits the Sun at a distance of 2.9–3.5 AU once every 5 years and 9 months (2,104 days). Its orbit is tilted by 17 degrees to the plane of the ecliptic and shows an eccentricity of 0.08. The body takes about 16.4 hours to rotate once around its axis,[6] and has an albedo of 0.06, according to the surveys carried out by the Infrared Astronomical Satellite, IRAS, the Japanese Akari satellite, and the NEOWISE mission of the Wide-field Infrared Survey Explorer.[3][4][5]
The minor planet was named in honor of Finnish astronomer Heikki Alikoski (1912–1997), assistant to the discoverer from 1937 to 1956, and himself an observer and discoverer of minor planets. He also helped greatly in establishing the Turku Astronomical-Optical Institute.[2]
