(52747) 1998 HM151, also written as (52747} 1998 HM151, is a cubewano. It has a perihelion (closest approach to the Sun) at 41.902 AU and an aphelion (farthest approach from the Sun) at 47.500 AU. It is 116 km in diameter. It was discovered on April 29, 1998 at the Mauna Kea Observatory, Hawaii.
Due to its small size, it is unlikely to be classified as a dwarf planet.
