(90568) 2004 GV9 (also written (90568) 2004 GV9) is a trans-Neptunian object that was discovered on April 13, 2004 by NEAT.[1] It is currently listed as a cubewano by the Minor Planet Center.[2]
It is very likely a dwarf planet.[9] A diameter of 680±34 km has been calculated from combined observations of the Herschel and Spitzer space telescopes.[5] 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.[10]
It has been observed forty-seven times, with precovery images back to 1954.[4]
