Eukelade /juːˈkɛlədiː/, also known as Jupiter XLVII, is a retrograde irregular satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2003, and received the temporary designation S/2003 J 1.[4][5][6]
Eukelade is about 4 kilometres in diameter, and orbits Jupiter at an average distance of 23,484,000 km in 693.02 days, at an inclination of 164° to the ecliptic (165° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.2829.
It was named in March 2005 after Eucelade - according to John Tzetzes, listed by some (unnamed) Greek writers as one of the Muses.[7]
Eukelade belongs to the Carme group, made up of irregular retrograde moons orbiting Jupiter at a distance ranging between 23 and 24 Gm and at an inclination of about 165°.
