What is "iocaste"

Iocaste ( ; Greek: Ιοκάστη), also known as , is a retrograde irregular satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2000, and given the temporary designation .

Iocaste orbits Jupiter at an average distance of 20,723 Mm in 609.427 days, at an inclination of 147° to the ecliptic (146° to Jupiter's equator) with an eccentricity of 0.2874.

It was named in October 2002 after Jocasta, the mother/wife of Oedipus in Greek mythology.

Iocaste belongs to the Ananke group, believed to be the remnants of a break-up of a captured heliocentric asteroid.

The satellite is about 5 kilometres in diameter and appears grey ( colour indices B−V=0.63, R−V=0.36), similar to C-type asteroids.
