It was named in 2005 after [[Arche (mythology)|Arche]], whom some Greek writers described as one of the four original [[Muse]]s, an addition to the earlier three ([[Aoede]], [[Melete]], and [[Mneme]]).<ref>[http://cfa-www.harvard.edu/iauc/08500/08502.html IAUC 8502: ''Satellites of Jupiter''] 2005 March 30 (naming the moon)</ref> Arche belongs to the [[Carme group]], made up of non-[[Sphere|spherical]] retrograde moons orbiting Jupiter at a distance ranging between 23,000,000 and 24,000,000 km and at an inclination of about 165°. == References == {{reflist}} {{Moons of Jupiter}} {{sci-stub}} [[Category:Jupiter's moons]]
