(574372) 2010 JO179 (provisional designation 2010 JO179) is a large, high-order resonant trans-Neptunian object in the outermost regions of the Solar System, approximately 700 kilometers (430 miles) in diameter.[6] Long-term observations suggest that the object is in a meta-stable 5:21 resonance with Neptune.[6] Other sources classify it as a scattered disc object.[4][5] It is possibly large enough to be a dwarf planet.[6]
