2067 Aksnes, provisional designation 1936 DD, is a rare-type Hildian asteroid from the outermost region of the asteroid belt, approximately 44 kilometers in diameter. The asteroid was discovered on 23 February 1936, by Finnish astronomer Yrjö Väisälä at Turku Observatory in Southwest Finland.[9] It was named after astronomer Kaare Aksnes.[2]
Aksnes is a member of the Hilda family, the outermost orbital group of asteroids in the main-belt, that are thought to have originated from the Kuiper belt. It orbits the Sun at a distance of 3.2–4.7 AU once every 7 years and 11 months (2,882 days). Its orbit has an eccentricity of 0.18 and an inclination of 3° with respect to the ecliptic.[1]
The asteroid's observation arc begins on its discovery night at Turku, the first used observation.[9] As all Hildian asteroids orbit in a 3:2 orbital resonance with the gas giant Jupiter, meaning that for every 2 orbits Jupiter completes around the Sun, they will complete 3 orbits,[1] this asteroid's orbit does not cross the path of any of the planets and therefore it will not be pulled out of orbit by Jupiter's gravitational field. As a result of this, it is likely that the asteroid will remain in a stable orbit for thousands of years.
