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

Orbit data

Kale orbits Jupiter at a mean distance of 23,217,000 km in 729 days, 11 hours and 17 minutes. The track has an eccentricity of 0.2599. With an inclination of 164.996 °, the orbit is retrograde; that is, the moon moves around the planet against the direction of rotation of Jupiter.

Due to its orbital properties, Kale is assigned to the Carme group , named after the Jupiter moon Carme .

Physical data

Kale has a mean diameter of about 2 km. Their density is estimated at 2.6 g / cm³. It is probably made up mainly of silicate rock. Kale 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 23.0 m .
