(91133) 1998 HK151, also written as (91133) 1998 HK151 is a resonant
Mauna Kea Observatory on 28 April 1998.[1]
Description
1998 HK151 is classified as a plutino, a dynamical group named after Pluto. Members of this group stay in a 2:3 resonance with Neptune.
1998 HK151 has the lowest, and thus bluest measured B-V color index of any TNO. On 24 May 2000, 1998 HK151 set a TNO record low B-V of 0.51. Reddening of the spectrum is caused by cosmic irradiaton 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
albedo
of 0.09.
