Callirrhoe (; Greek: Καλλιρρόη ), also known as Jupiter XVII Jupiter 's outer natural satellites . It is an irregular moon that orbits in a retrograde direction. Callirrhoe was imaged by Spacewatch at Kitt Peak National Observatory from October 6 through November 4, 1999,[8] asteroid 1999 UX18 .[9] [10] Tim Spahr on July 18, 2000, and then given the designation S/1999 J 1 [1] [11] [8]

It was named in October 2002 after Callirrhoe , daughter of the river god Achelous , one of Zeus 's (Jupiter's) many conquests.[12]
Characteristics [ edit ]
Callirrhoe has an apparent magnitude of 20.8,[7] dwarf planet Eris at magnitude 18.7.[13] [b]
Callirrhoe is about 9.6 kilometers in diameter,[6] inclination of 141° to the ecliptic (140° to Jupiter's equator) with an eccentricity of 0.28. This object was probably captured long ago from a heliocentric orbit and the Sun's gravitational influence makes this orbit highly erratic.[8]
It belongs to the Pasiphae group , irregular retrograde moons orbiting Jupiter at distances ranging between 22.8 and 24.1 million kilometers, and with inclinations ranging between 144.5° and 158.3°. However, while Pasiphae is gray (B−V=0.74, V−R=0.38, V−I=0.74) in color, Callirrhoe is light red (B−V=0.72, V−R=0.50, V−I=1.02) and more similar to Megaclite .[14]
Exploration [ edit ]
