(90568) 2004 GV9 (provisional designation2004 GV9) is a trans-Neptunian object that was discovered on April 13, 2004 by NEAT.[1] It has been listed as a cubewano by the Minor Planet Center.[2] It was discovered on 13 April 2004 by NEAT. It has been observed forty-seven times, with precovery images back to 1954.[4] The object has an orbital period of 273.88 years. Its maximum distance from the Sun (aphelion) is 45.62 AU, and its closest (perihelion) is 38.7 AU. It has an inclination of 21.9718° and an eccentricity of 0.082.
M. E. Brown estimates that is very likely a dwarf planet.[9] A diameter of 680±34 km has been determined from combined observations of the Herschel and Spitzer space telescopes.[5] Tancredi notes that 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] However, its low albedo suggests it has never been resurfaced and thus is unlikely to have planetary geology.
