It measures approximately 134 kilometers in diameter. It was discovered by astronomers at the Mauna Kea Observatory on 28 April 1998. Description 1998 HK 151 is classified as a plutino, a dynamical group named after Pluto. Members of this group stay in a 2:3 resonance with Neptune. 1998 HK 151 has the lowest, and thus bluest measured B-V color index of any TNO. On 24 May 2000, 1998 HK 151 set a TNO record low B-V of 0.51. Reddening of the spectrum is caused by ultraviolet radiation and charged particles. Becoming bluer in the spectrum is caused by impact collisions exposing the interior of an object. Based on an absolute magnitude of 7.62, Johnston's Archive estimates a diameter of 134 kilometers, assuming an albedo of 0.09.
