Ilmarë
Sign in to saveAlso known as (174567) Varda I Ilmarë, Varda I
Ilmarë, formal designation '''''', is the only known moon of the large Kuiper belt object 174567 Varda. It was discovered by Keith Noll et al. in 2009, at a separation of about 0.12 arcsec, using discovery images taken by the Hubble Space Telescope on 26 April 2009, and reported in 2011. At approximately 403 km in diameter (about 45% that of its primary), it is the fourth-largest known moon of a trans-Neptunian object, after Pluto I Charon, Eris I Dysnomia, and Orcus I Vanth. Assuming that Ilmarë has the same albedo and density as Varda, Ilmarë would constitute approximately 8.4% of the s

Ilmarë ist ein Mond des transneptunischen Objektes Varda im Kuipergürtel, das bahndynamisch als „heißes“ Cubewano oder als erweitertes Scattered Disk Object (DO) eingestuft wird. Der Begleiter weist mit 326 km etwa die Hälfte des Durchmessers des Mutterasteroiden auf. Da beide Himmelskörper um den gemeinsamen Schwerpunkt kreisen, kann das System auch als Doppelasteroiden-System aufgefasst werden.
