(130391) 2000 JG81, also written as 2000 JG81, is a trans-Neptunian object that resides in the Kuiper belt. It was discovered on 6 May 2000 at the La Silla Observatory in Chile.[4]
It is in a 2:1 orbital resonance with the planet Neptune.
When it was first discovered in 2000, it was assumed to be a plutino at perihelion.[5]
