379 Huenna
Huenna is a large asteroid orbiting in the asteroid belt. It is part of the Themis family, and thus a C-type asteroid and consequently composed mainly of carbonaceous material.
It was discovered by Auguste Charlois on 8 January 1894 in Nice. It is named after the Swedish island of Hven, the site of two observatories.
A satellite, 7 km across and designated S/2003 1, was discovered on 14 August 2003 by Jean-Luc Margot using the Keck II adaptive optics telescope at Mauna Kea. The moon orbits 3400±11 km away in 80.8±0.36 d with an eccentricity of 0.334±0.075. The system is loosely bound as Huenna has a Hill sphere with a radius of about 20,000 km.
