Jupiter LII (provisional designation S / 2010 J 2 ) is one of the smaller moons of the planet Jupiter .
discovery
Jupiter LII was discovered on September 8, 2010 by the French astronomer Christian Veillet and was given the provisional designation S / 2010 J 2. The moon has not yet been given an official name - the moons of Jupiter are usually female figures from Greek mythology - and is called Jupiter LII according to the system of the International Astronomical Union (IAU).
Orbit data
Jupiter LII orbits Jupiter with a major semi-axis of about 20 million kilometers in almost 600 days. The orbit has an eccentricity of 0.31. With an inclination of around 150 ° to the ecliptic , the orbit is retrograde , i.e. that is, the moon moves around the planet against the direction of rotation of Jupiter.
Physical data
Jupiter LII has a diameter of about 1 km.
