Kale is about 2 kilometres (1.2 miles) in diameter, and orbits Jupiter at an average distance of 22,409 Mm (13,924,000 mi) in 736.55 days, at an inclination of 165° to the ecliptic (166° to Jupiter's equator), in a retrograde direction and with an orbital eccentricity of 0.2011.

It was named in August 2003[7] after Kale, one of the Charites (Greek: Χάριτες, Latin: Gratiae, 'Graces'), daughters of Zeus (Jupiter). Kale is the spouse of Hephaestus according to some authors (although most have Aphrodite play that role).

It belongs to the Carme group, made up of irregular retrograde moons orbiting Jupiter at a distance ranging between 23 and 24 Gm (14,000,000–15,000,000 mi) and at an inclination of about 165°.
