Kuiper Belt Object (90568) 2004 GV9 (also written (90568) 2004 GV9) is a trans-Neptunian object. It was discovered on April 13, 2004 by NEAT. It is currently listed as a cubewano by the Minor Planet Centre. It is very likely a dwarf planet. The Spitzer Space Telescope has estimated it to have a diameter of 677±70 km. Light-curve-amplitude analysis shows only small deviations, suggesting that 2004 GV9 is a spheroid with small albedo spots and hence a dwarf planet. Read more
