Kallichore (moon)
Encyclopedia
Kallichore also known as , is a natural satellite
of Jupiter
. It was discovered by a team of astronomers from the University of Hawaii
led by Scott S. Sheppard
, et al. in 2003. It received the temporary designation .
Kallichore is about 2 kilometres in diameter, and orbits Jupiter at an average distance of 23,112 Mm in 717.806 days, at an inclination
of 165° to the ecliptic
(164° to Jupiter's equator), in a retrograde
direction and with an eccentricity of 0.2042.
It was named in March 2005 after the nymph Kallichore
.
Kallichore belongs to the Carme group
, made up of irregular retrograde moons orbiting Jupiter at a distance ranging between 23 and 24 Gm and at an inclination of about 165°.
Natural satellite
A natural satellite or moon is a celestial body that orbits a planet or smaller body, which is called its primary. The two terms are used synonymously for non-artificial satellites of planets, of dwarf planets, and of minor planets....

Ecliptic
The ecliptic is the plane of the earth's orbit around the sun. In more accurate terms, it is the intersection of the celestial sphere with the ecliptic plane, which is the geometric plane containing the mean orbit of the Earth around the Sun...

Retrograde motion
Retrograde motion is motion in the direction opposite to the movement of something else, and is the contrary of direct or prograde motion. This motion can be the orbit of one body about another body or about some other point, or the rotation of a single body about its axis, or other phenomena such...

Kallichore (mythology)
In Greek mythology, Kallichore is sometimes considered one of the Muses, and thus a daughter of Zeus ; a scholion to Hesiod's Works and Days names her. She is better known, however, as one of the Nysiads, nymphs who nursed Dionysos. Both the lunar crater Kallichore and Jupiter's moon Kallichore...
