Vanth is one of the newly discovered moons in the Kuiper Belt. So far it is the only moon of the dwarf planet Orcus.
2005 was the year that Vanth was found. Michael Brown and T.A. Suer are the two who are credited with its discovery.
Vanth is a relatively small moon at just 370 kilometres (230 miles) in width though it may be up to 100 kilometres larger or smaller. It orbits dwarf planet Orcus at a distance of roughly 900 kilometres (560 miles) taking over nine and a half Earth days to do so.
Like all of the Kuiper Belt objects Vanth is unbelievably cold at 44 degrees Kelvin (minus 230 degrees Celsius).
Vanth is thought to have been a Kuiper Belt object that was captured by dwarf planet Orcus. It is believed that Orcus originally rotated at a much faster rate than it does at present. This would have facilitated the capture of a body as large as Vanth.
The Name Vanth
Sonya Taaffe proposed the name Vanth after Michael Brown asked for suggestions. The moon is named after one of the Etruscan’s gods. These Iron Age people believed that Vanth was a spirit who acted as a guide for the deceased in the underworld.
