Mneme (moon)

Mneme (nee'-mee, Greek Μνήμη) is a natural satellite of Jupiter. It orbits Jupiter at a distance of roughly 20.6 Gm. Mneme is about 2 kilometres in diameter.

It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard, et al. in 2003, and was provisionally designated S/2003 J 21. It is also designated Jupiter XL.

It is named after Mneme , one of the three original Muses. She is sometimes confused with Mnemosyne, mother of the Muses (the three or the nine, depending on the author) by Zeus (Jupiter).

Mneme belongs to the Ananke group, retrograde irregular moons which orbit Jupiter between 19.3 and 22.7 Gm, at inclinations of roughly 150°.
