Aoede or Jupiter XLI, is a moon of Jupiter. It was found by a team of astronomers from the University of Hawaiʻi led by Scott S. Sheppard in 2003. It received the designation S/2003 J 7.[5][6]

Aoede is about 10 km (6.2 mi) in diameter, and orbits Jupiter at an average distance of 23,044,000 km (14,319,000 mi) in 714.657 days, at an inclination of 160° to the ecliptic (162° to Jupiter's equator), 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 Pasiphaë group, non-spherical retrograde moons orbiting Jupiter at distances ranging between 22,800,000 km (14,167,300 mi) and 24,100,000 km (14,975,000 mi), and with inclinations ranging between 144.5° and 158.3°.
