Template:Mp (provisional designation Template:Mp) is a large trans-Neptunian object that resides in the scattered disc region beyond the Kuiper belt. It was discovered on 9 September 2005, by American astronomers Andrew Becker, Andrew Puckett and Jeremy Kubica at Apache Point Observatory in Sunspot, New Mexico. It measures approximately 600 kilometers in diameter.

Description

Template:Mp has been observed 303 times over 17 oppositions, with precovery images dating back to 1976.[2][3] The orbit is well determined with an uncertainty parameter of 2.[2]

In 2018, two stellar occultations by Template:Mp were observed on 3 February and 24 December.[4] The February occultation yielded a single chord length of Template:Cvt.[5] Observations of the December occultation yielded two positive chords, which together suggest an approximate diameter of Template:Cvt.[6] Johnston's Archive estimates Template:Mp to be 584 km in diameter, based on an absolute magnitude of 4.4 and an assumed albedo of 0.09.[7]
