Eukelade Template:IPAc-en, also known as Jupiter XLVII, is a retrograde irregular satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaiʻi led by Scott S. Sheppard in 2003, and received the temporary designation S/2003 J 1.[1][2][3]
Eukelade is about 4 kilometres in diameter, and orbits Jupiter at an average distance of 22.5 million km in 689 days, at an inclination of 165° to the ecliptic, in a retrograde direction and with an eccentricity of 0.363.[4] Eukelade next comes to apojove (farthest distance from Jupiter) on 17 January 2026 when it will be Script error: No such module "convert". from Jupiter.[5]
It was named in March 2005 after Eucelade - according to John Tzetzes, listed by some (unnamed) Greek writers as one of the Muses.[6] The name ends in an "e" because the orbit is retrograde.
Eukelade belongs to the Carme group, made up of irregular retrograde moons orbiting Jupiter at a distance ranging between 23 and 24 million km and at an inclination of about 165°.
