(445473) 2010 VZ98 is a trans-Neptunian object (TNO) orbiting the Sun in the scattered disc. It was discovered in November 2010 when it was 38 AU from the Sun. With an absolute magnitude of 5.0,[5] it is likely a dwarf planet and might be around 500 kilometres (310 mi) in diameter.[4]
Small number statistics suggest (445473) 2010 VZ98 may be trapped in a 3:2 orbital resonance with an unseen planet beyond Neptune with a semi-major axis of 195–215 AU.[6]
