(91205) 1998 US43, also written as a (91205) 1998 US43 is a plutino, so it has a 2:3 resonance with Neptune, similar to Pluto. It has a perihelion (closest approach to the Sun) at 34.002 AU and an aphelion (farthest approach from the Sun) at 44.220 AU . It is about 116 km in diameter, so it is unlikely to ever be classified as a dwarf planet due to its relatively small size. It was discovered on October 22, 1998, by Marc W. Buie.
