Trans-Neptunian object
(84922) 2003 VS2 trans-Neptunian object discovered by theNear-Earth Asteroid Tracking program on 14 November 2003.[ 1] Pluto , it is in a 2:3orbital resonance withNeptune [ 3] [ 4] plutino . It has an elongated ellipsoidal shape.[ 5]
LikePluto ,2003 VS2 is locked in the3:2 mean-motion resonance with Neptune , although its orbit is both less inclined and significantly less eccentric than Pluto's.[ 2]
2003 VS2 has a highlight curve amplitude of± 0.01[ 5] ± 0.02 h[ 9]
Physical characteristics [ edit ] 2003 VS2 has a moderately red surface with amoderately red color indices B−V=0.93, V−R=0.59.[ 11] [ 6]
In 2007, its diameter was initially estimated by theSpitzer Space Telescope at± 200 km[ 12] +35.1 Herschel Space Telescope observations.[ 7] 2003 VS2 was found to beellipsoidal in shape based onstellar occultations that occurred in 2013 and 2014;[ 6] [ 13] 2003 VS2 are estimated at+29.5 [ 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 TNOs,[ 14] × 10
