Orthosie (moon)

From Simple English Wikipedia, the free encyclopedia

Orthosie or Jupiter XXXV, is a moon of Jupiter. It was found by a team of astronomers from the University of Hawaii led by Scott Sheppard in 2001, and given the designation S/2001 J 9.[1][2]

Orthosie is about 2 kilometres in diameter, and orbits Jupiter at an average distance of 20,568,000 km in 602.619 days, at an inclination of 142° to the ecliptic (143° to Jupiter's equator), with an orbital eccentricity of 0.2433.

It was named in August 2003 after Orthosie, the Greek goddess of prosperity and one of the Horae.[3] The Horae (Hours) were daughters of Zeus and Themis.

Orthosie belongs to the Ananke group, retrograde non-spherical moons which orbit Jupiter between 19,300,000 and 22,700,000 km, at inclinations of about 150°.
