1460 Haltia, provisional designation 1937 WC, is a stony background asteroid from the central regions of the asteroid belt, approximately 8 kilometers in diameter. It was discovered on 24 November 1937, by Finnish astronomer Yrjö Väisälä at the Iso-Heikkilä Observatory in Turku, Finland. [10] The asteroid was named after Halti (Haltia), Finland's highest peak on the border to Norway. [2]
Haltia is a non- family asteroid of the main belt's background population. [3] It orbits the Sun in the central asteroid belt at a distance of 2.1–3.0 AU once every 4 years and 1 month (1,481 days). Its orbit has an eccentricity of 0.19 and an inclination of 7 ° with respect to the ecliptic. [1] The body's observation arc begins with its official discovery observation at Turku. [10]
Haltia is an assumed stony S-type asteroid. [7]
Two rotational lightcurves of Haltia were obtained from photometric observations by astronomers Henk de Groot, Raoul Behrend and René Roy. Lightcurve analysis gave a respective rotation period of 3.58682 and 3.588 hours with a brightness amplitude of 0.32 magnitude ( U=3-/3). [8] The Lightcurve Data Base adopts a consolidated period of 3.59 hours. [7]
According to the surveys carried out by the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Haltia measures between 6.57 and 8.44 kilometers in diameter and its surface has an albedo between 0.186 and 0.36. [4] [5] [6]
The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 8.97 based on an absolute magnitude of 12.6. [7]
This minor planet was named after Halti (Haltia), the highest Finnish peak at 1,365 metres (4,478 ft) located on the border between Norway and Finland. [2] The official naming citation was published by the Minor Planet Center on 20 February 1976 ( M.P.C. 3928). [11]
