(84922) 2003 VS₂ is a trans-Neptunian object discovered by the Near Earth Asteroid Tracking program on 14 November 2003.^[1] Like Pluto, it is in a 2:3 orbital resonance with Neptune^[3][4] and is thus a plutino. Analysis of light-curve suggests that it is not a dwarf planet.^[11]

Like Pluto, (84922) 2003 VS₂ is locked in the 3:2 mean-motion resonance with Neptune, although its orbit is both less inclined and significantly less eccentric than Pluto's.^[2]

(84922) 2003 VS₂ has a significant light-curve amplitude of 0.21±0.01. The most likely value of the rotation period is 7.41±0.02 h.^[9]

(84922) 2003 VS₂ has a moderately red surface with a moderately red color indices B−V=0.93, V−R=0.59.^[12] Its geometrical albedo is about 0.13.^[6]

In 2007, its diameter was initially estimated by the Spitzer Space Telescope at 725±200 km.^[13] However, in 2012, this was reduced to 523.0+35.1
−34.4 km after new Herschel Space Telescope observations.^[7] In 2019, 2003 VS₂ was found to be ellipsoidal in shape based on stellar occultations that occurred in 2013 and 2014;^[6] the light curve derived from the occultations suggests that this plutino is not in hydrostatic equilibrium and hence not a dwarf planet.^[14] The dimensions of 2003 VS₂ are estimated at 627.6 km × 531 km × 494.6 km, with a volume-equivalent diameter 548.3+29.5
−44.6 km.^[6] 2003 VS₂ has no known satellite that can be used to directly determine its mass, but assuming a density of 1 g/cm³, typical of mid size TNO's,^[15] gives a mass estimate of about 7.5×10¹⁹ kg.
