Kore /ˈkɔːriː/, also known as Jupiter XLIX, is one of the outermost named natural satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaiʻi led by Scott S. Sheppard in 2003 and given the provisional designation S/2003 J 14 until its naming in 2007.^[4]^[5]^[6] It was the 49th moon of Jupiter discovered.^[7]

Kore is about 2 kilometers in diameter, and orbits Jupiter at an average distance of 24 million km in 751 days, at an inclination of 139°, in a retrograde direction and with an eccentricity of 0.409.^[2]

It belongs to the Pasiphae group, which is made up of irregular retrograde moons orbiting Jupiter at distances ranging between 22.8 and 24.1 million km, and with inclinations ranging between 144.5° and 158.3°.

It was named after Kore, another name for the Greek goddess Persephone (from the Greek κόρη, "daughter [of Demeter]").^[6]
