Template:Mp (provisional designation Template:Mp) is a trans-Neptunian object that was discovered in 1996 by Chadwick Trujillo, David Jewitt and Jane Luu. Until 20000 Varuna was discovered, it was the second-largest known object in the Kuiper belt, after Pluto.
Origin

Based on their common pattern of IR water-ice absorptions, neutral visible spectrum[1] and the clustering of their orbital elements, the other KBOs Template:Mpl, Template:Mpl, Template:Mpl and Template:Mpl all appear to be collisional fragments broken off of the dwarf planet Template:Dp.
Orbit
The eccentricity of Template:Mp varies between ca. 0.110 and 0.125 every 2 million years, with additional variations on the order of ± 0.01 on much shorter time scales. It is in an intermittent 19:11 resonance with Neptune. The resonance breaks every 2 million years when the eccentricity is highest and the orbit is closest to Neptune.[2]
