Taygete (Jupiter Moon XX) is one of the smaller outer moons of the planet Jupiter .
discovery
Taygete was discovered by astronomers at the University of Hawaii on November 25, 2000 . It was initially given the provisional designation S / 2000 J 9.
The moon was named after Taygete , one of the Pleiades and lover of Zeus from Greek mythology .
Orbit data
Taygete orbits Jupiter at a mean distance of 23,360,000 km in 732 days and 5 hours. The track has an eccentricity of 0.252. With an inclination of 165.2 ° the orbit is retrograde, that is, the moon moves around the planet against the direction of rotation of Jupiter.
Due to its orbital properties, Taygete is assigned to the Carme group , named after the Jupiter moon Carme .
Physical data
Taygete has a diameter of about 5 km. Its density is estimated at 2.6 g / cm³. It is probably made up mainly of silicate rock. Taygete has a very dark surface with an albedo of 0.04, i.e. that is, only 4% of the incident sunlight is reflected. Its apparent brightness is 21.9 m .
