(90568) 2004 GV9 (also written (90568) 2004 GV9) is a trans-Neptunian object that was discovered on April 13, 2004 by NEAT. It is currently listed as a cubewano by the Minor Planet Center.
It is very likely a dwarf planet. A diameter of 7005680000000000000♠680±34 km has been calculated from combined observations of the Herschel and Spitzer space telescopes. Light-curve-amplitude analysis shows only small deviations, suggesting that (90568) 2004 GV9 could be a spheroid with small albedo spots and hence a dwarf planet.
It has been observed forty-seven times, with precovery images back to 1954.
