379 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 January 8, 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 (379) 1, was discovered on August 14, 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.
