Template:Nowrap is a natural satellite of Jupiter. It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2003.<ref>IAUC 8087: Satellites of Jupiter 2003 March 4 (discovery)</ref><ref name="MPEC-2003-E11">MPEC 2003-E11: S/2003 J 1, 2003 J 2, 2003 J 3, 2003 J 4, 2003 J 5, 2003 J 6, 2003 J 7 2003 March 4 (discovery and ephemeris)</ref>

Template:Nowrap is about 2 km in diameter, and orbits Jupiter at an average distance of 23,000,000 km in 669 days, at an inclination of 149° to the ecliptic, in a retrograde direction and with an eccentricity of 0.497.

It belongs to the Pasiphae group, irregular retrograde moons orbiting Jupiter at distances ranging between 22.8 and 24.1 Gm, and with inclinations ranging between 144.5° and 158.3°.
