Dia (S/2000 J 11) ls the second-outermost prograde non-spherical moon of Jupiter. It was found by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2000.
Dia is about 4 kilometres in diameter, and orbits Jupiter at an average distance of 12,555,000 km in 287 days, at an inclination of 28° (to Jupiter's equator), and with an orbital eccentricity of 0.248.
The moon is included in the Himalia group. After discovery it was lost for ten years because the orbit was poorly known. Recovery allowed much better precision.

Dia imaged by the Canada-France-Hawaii Telescope in December 2001. In the second frame Dia is not visible due to Jupiter's glare reducing the relative brightnesses of the stars.
