'''Eukelade''' {{IPAc-en|j|uː|ˈ|k|ɛ|l|ə|d|iː}}, also known as '''{{nowrap|Jupiter XLVII}}''', is a [[retrograde motion|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 '''{{nowrap|S/2003 J 1}}'''.<ref>[http://www.cbat.eps.harvard.edu/iauc/08000/08087.html IAUC 8087: ''Satellites of Jupiter''] 2003 March 4 (discovery)</ref><ref>[http://cfa-www.harvard.edu/iau/mpec/K03/K03E11.html MPEC 2003-E11: ''S/2003 J 1, 2003 J 2, 2003 J 3, 2003 J 4, 2003 J 5, 2003 J 6, 2003 J 7''] 2003 March 4 (discovery and ephemeris)</ref><ref>[http://cfa-www.harvard.edu/mpec/K03/K03E29.html MPEC 2003-E29: ''S/2003 J 9, 2003 J 10, 2003 J 11, 2003 J 12; S/2003 J 1, 2003 J 6''] 2003 April 3 (revised ephemeris)</ref>

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 motion|retrograde]] direction and with an [[eccentricity (orbit)|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 [[Muse]]s.<ref>* Marta Cardin, Olga Tribulato: ''Enumerating the Muses: Tzetzes in Hes. Op. 1 and the Parody of Catalogic Poetry in Epicharmus.'' In: Marco Ercoles, Lara Pagani, Filippomaria Pontani, Giuseppe Ucciardello: ''Approaches to Greek Poetry: Homer, Hesiod, Pindar, and Aeschylus in Ancient Exegesis'' (= ''Trends in Classics.'' Supplementary Volumes 73). De Gruyter, Berlin/Boston 2019, p. 161–192; here p. 171.</ref>

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°.
