Eurydome (also Jupiter XXXII) is one of the smaller outer moons of the planet Jupiter .

discovery

Eurydome was discovered on December 9, 2001 by astronomers at the University of Hawaii. It was initially given the provisional designation S / 2001 J 4.

The moon was named after Eurydome , one of the Charites from Greek mythology .

Orbit data

Eurydome orbits Jupiter at an average distance of 22,865,000 km in 717 days and 7 hours. The track has an eccentricity of 0.276. With an inclination of 150.3 ° the orbit is retrograde; that is, the moon moves around the planet against the direction of rotation of Jupiter.

Due to its orbital properties, Eurydome is assigned to the Pasiphae group , named after the Jupiter moon Pasiphae . Eurydome is the innermost member of the group.

Physical data

Eurydome has a mean diameter of about 3 km. Their density is estimated at 2.6 g / cm³. It is probably made up mainly of silicate rock. Eurydome 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 22.7 m .
