Шаблон:Mp is a trans-Neptunian object and possibly a cubewano from the outermost regions of the Solar System, approximately 480 kilometers in diameter. It was discovered on 11 January 2008, by American Michael E. Brown and Megan Schwamb at Palomar Observatory in California.[1]
Description
Шаблон:Mp orbits the Sun at a distance of 35.8–47.5 AU once every 267 years and 11 months (98,249 days; semi-major axis of 41.70 AU). Its orbit has an eccentricity of 0.14 and an inclination of 27° with respect to the ecliptic.[2] It has 3 precovery observations back to 1989.[1] Lightcurve analysis gave an ambiguous rotation period of 9.04 hours with a brightness amplitude of 0.12 magnitude (Шаблон:Small).[3][4] Шаблон:Mp has been identified as a member of the Haumea family in a dynamical study led by Proudfoot and Ragozzine in 2019.[5]
Origin
Based on their common pattern of infrared water-ice absorption and the clustering of their orbital elements, the other KBOs, it appear to be collisional fragments broken off the dwarf planet Шаблон:Dp. The neutral color of the spectrum of these objects in the visible range evidences a lack of complex organics on the surface of these bodies that has been studied in detail for the surface of Haumea.Шаблон:Citation needed
Numbering and naming
This minor planet was numbered by the Minor Planet Center on 7 February 2012.[6] As of 2023, it has not been named.[1]
