Kalyke Template:IPAc-en, also known as Template:Nowrap, is a retrograde irregular satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2000, and given the temporary designation Template:Nowrap.<ref>IAUC 7555: Satellites of Jupiter Template:Webarchive 2001 January 5 (discovery)</ref><ref name="MPEC-2001-A28">MPEC 2001-A28: S/2000 J 2, S/2000 J 3, S/2000 J 4, S/2000 J 5, S/2000 J 6 2001 January 5 (discovery and ephemeris)</ref>
From infrared thermal measurements by the WISE spacecraft, Kalyke's albedo is measured at 2.9%, corresponding to a diameter of 6.9 kilometres.<ref name="Grav2015"/> It orbits Jupiter at an average distance of 23,181,000 km in 766.61 days, at an inclination of 166° to the ecliptic (165° to Jupiter's equator), in a retrograde direction and with an eccentricity of 0.2140.
It was named in October 2002 after the Greek mythological figure Kalyke or Calyce.<ref>IAUC 7998: Satellites of Jupiter 2002 October 22 (naming the moon)</ref>
It 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°. Kalyke is redder in color (B−V=0.94, V−R=0.70) than other moons of the Carme group, suggesting that it is a captured centaur or TNO, or a remnant of such an object that collided with the Carme group progenitor.<ref name="Grav2003">Template:Cite journal</ref>
