Huenna (

minor planet designation: 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

observatories. This island is where Tycho Brahe built his observatory.[6]

Satellite

A satellite, 7 km across and designated S/2003 (379) 1, was discovered on 14 August 2003 by Jean-Luc Margot using the Keck II adaptive optics telescope at Mauna Kea.[7] The moon orbits 3400±11 km away in 80.8±0.36 d with an eccentricity of 0.334±0.075.[5] The system is loosely bound[4] as Huenna has a Hill sphere with a radius of about 20,000 km.[2]
