(15810) 1994 JR1, also written as 1994 JR1, is a plutino, with 2:3 resonance with Neptune, similar to Pluto. It has a perihelion (closest approach to the Sun) at 34.756 AU and an aphelion (farthest distance from the Sun) at 44.507[2], so it is in a relatively eccentric orbit. It is about 127 km in diameter[2], so it is unlikely to be classified as a dwarf planet due to its relatively small size. It was discovered on May 12, 1994 by M. J. Irwin and A. Zytkow.[3]
