Kore (also Jupiter XLIX) is one of the smaller moons of the planet Jupiter .
discovery
Kore was discovered by astronomers at the University of Hawaii on February 8, 2003 . According to the system of the International Astronomical Union (IAU), the moon was provisionally designated as S / 2003 J 14 and was given the name Kore in 2007 after an alternative name for Persephone .
Orbit data
Kore orbits Jupiter at a mean distance of 24,543,000 km in 779.2 days. The orbit has an eccentricity of 0.325. With an incline of 145.0 °, the orbit is retrograde ; that is, the moon moves around the planet against the direction of rotation of Jupiter.
Due to its orbital properties, Kore is assigned to the Pasiphae group , named after the Jupiter moon Pasiphae .
Physical data
Kore has a diameter of about 2 km. Their density is estimated at 2.6 g / cm³. It is presumably composed predominantly of silicate rock and possibly has a very dark surface with an albedo of 0.04, i.e. that is, only 4% of the incident sunlight is reflected.
