Aoede /eɪˈiːdiː/, also known as Jupiter XLI, is a natural satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2003. It received the temporary designation S/2003 J 7.[5][6]
Aoede is about 10 kilometres in diameter, and orbits Jupiter at an average distance of 23,044,000 km in 714.657 days, at an inclination of 160° to the ecliptic (162° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.4311.
It was named in March 2005 after Aœde, one of the three original Muses. Aœde was the Muse of song, and was a daughter of Zeus (Jupiter) by Mnemosyne.[7]
Aoede belongs to the Pasiphae group, irregular retrograde moons orbiting Jupiter at distances ranging between 22.8 and 24.1 Gm, and with inclinations ranging between 144.5° and 158.3°.
