Isonoe (also Jupiter XXVI) is one of the smaller outer moons of the planet Jupiter .
discovery
Isonoe was discovered by astronomers at the University of Hawaii on November 23, 2000 . It was initially given the provisional designation S / 2000 J 6.
The moon was named after Isonoe , one of the Danaids and lover of Zeus from Greek mythology .
Orbit data
Isonoe orbits Jupiter at a mean distance of 23,155,000 km in 725 days and 12 hours. The track has an eccentricity of 0.246. With an incline of 165.2 ° the orbit is retrograde, i.e. that is, the moon moves around the planet against the direction of rotation of Jupiter.
Due to its orbital properties, Isonoe is assigned to the Carme group , named after the Jupiter moon Carme .
Physical data
Isonoe has a diameter of about 4 km. It is probably made up mainly of silicate rock. Isonoe 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 22.5 m .
