Helike (moon)
Helike (
/ˈhɛlɨkiː/ hel-ə-kee; Greek: Ελίκη), also known as Jupiter XLV, 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 S/2003 J 6.[1][2][3]
Helike is about 4 kilometres in diameter, and orbits Jupiter at an average distance of 20,540 Mm 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.
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, retrograde irregular moons which orbit Jupiter between 19.3 and 22.7 Gm, at inclinations of roughly 150°.
