'''Isonoe''' {{IPAc-en|aɪ|ˈ|s|ɒ|n|oʊ|.|iː}}, also known as '''{{nowrap|Jupiter XXVI}}''', is a retrograde irregular satellite of [[Astronomy:Jupiter|Jupiter]]. It was discovered by a team of astronomers from the [[Organization:University of Hawaii|University of Hawaii]] led by [[Biography:Scott S. Sheppard|Scott S. Sheppard]] in 2000, and given the temporary designation '''{{nowrap|S/2000 J 6}}'''.<ref>[http://www.cbat.eps.harvard.edu/iauc/07500/07555.html IAUC 7555: ''Satellites of Jupiter''] {{webarchive|url=https://web.archive.org/web/20020916000558/http://cfa-www.harvard.edu/iauc/07500/07555.html |date=2002-09-16 }} 2001 January 5 (discovery)</ref><ref name="MPEC-2001-A28">[http://minorplanetcenter.net//mpec/K01/K01A28.html MPEC 2001-A28: ''S/2000 J 2, S/2000 J 3, S/2000 J 4, S/2000 J 5, S/2000 J 6''] 2001 January 5 (discovery and ephemeris)</ref>

Isonoe is about 4 kilometres in diameter, and orbits Jupiter at an average distance of 23,833,000 km in 688.61 days, at an inclination of 166° to the [[Astronomy:Ecliptic|ecliptic]] (169° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.166.

It was named in October 2002 after Isonoe, one of the Danaïdes in Greek mythology, and a lover of [[Religion:Zeus|Zeus]] (Jupiter).<ref>[http://www.cbat.eps.harvard.edu/iauc/07900/07998.html IAUC 7998: ''Satellites of Jupiter''] 2002 October 22 (naming the moon)</ref>

Isonoe belongs to the [[Astronomy:Carme group|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°.
