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 Hawaiʻi led by Scott S. Sheppard in 2003. It received the temporary designation S/2003 J 7.[7][8]
Aoede is about 4 kilometres in diameter,[4] with an estimate as high as 10 km.[6] The 4 km Minor Planet Center estimate is based on 74 observations for the absolute magnitude (H), while the 10 km estimate is based on 6 observations.
Aoede orbits Jupiter at an average distance of 24 million km in 762 days, at an inclination of 158°, in a retrograde direction and with an eccentricity of 0.432.[4]
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.[9]
Aoede belongs to the Pasiphae group, irregular retrograde moons orbiting Jupiter at distances ranging between 22.8 and 24.1 million km, and with inclinations ranging between 144.5° and 158.3°.
