Kallichore is ∼3 kilometers in size and thus one of the small known Irregular moons of Jupiter. It has been discovered with the Canada-France-Hawaii Telescope on Mauna Kea in February 2003 by a group of astronomers led by S. Sheppard; the discovery announcement followed in March 2003 joint with 20 other outer Jovian moons. The mean distance of Kallichore to Jupiter is ∼23 million kilometers, with one revolution around the planet on a retrograde orbit requiring 1 year, 8 months and 2 weeks.
In early October 2031, the Juice spacecraft of the European Space Agency (ESA) will come closer than 0.6 million kilometers to Kallichore. This will be the closest approach of Juice to any Irregular Jovian moon.
