Helike Шаблон:IPAc-en, also known as Шаблон:Nowrap, is a moon of Jupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2003, and given the temporary designation Шаблон:Nowrap.[1][2][3]

Helike is about 4 kilometres in diameter, and orbits Jupiter at an average distance of 20.54 million kilometres in 601.402 days, at an inclination of 155° to the ecliptic (156° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.1375. Its average orbital speed is 2.48 km/s.

It was named in March 2005 after Helike, one of the nymphs that nurtured Zeus (Jupiter) in his infancy on Crete.[4]

Helike belongs to the Ananke group.
