Aoede (also Jupiter XLI) is one of the smaller moons of the planet Jupiter .

discovery

Aoede was discovered by astronomers at the University of Hawaii on February 8, 2003 . The moon was named Aoede (after the muse Aoide ) on March 30, 2005 by the International Astronomical Union (IAU).

Orbit data

Aoede orbits Jupiter at an average distance of 23,980,000 km in 761.5 days. The track has an eccentricity of 0.4322. With an inclination of 158.257 °, the orbit is retrograde; that is, the moon moves around the planet against the direction of rotation of Jupiter.

Due to its orbital properties, Aoede is assigned to the Pasiphae group , named after the Jupiter moon Pasiphae .

Physical data

Aoede has a diameter of about 4 km. Its density is estimated at 2.6 g / cm³, provided that it is mainly composed of silicate rock. It has a very dark surface with an albedo of 0.04, i.e. that is, only 4% of the incident sunlight is reflected. Their apparent brightness is 22.5 ^m .
