 However, Grundy et al.conclude that objects such as this, in the size range of 400–1000 km, with albedos less than ≈0.2 and densities of ≈1.2 g/cm3 or less, have likely never compressed into fully solid bodies, let alone differentiated or collapsed into hydrostatic equilibrium, and so are highly unlikely to be dwarf planets.It is possibly the largest unnamed object in the Solar System, given the large measurement uncertainties of all unnamed objects with greater best-estimate diameters.
