   Based on the given absolute magnitude, and given how exceptionally red it looked in 2014 precovery images from CFHT (the g - r color was 0.9, and r - i was 0.5!) I would estimate at an albedo of 0.01-0.08 a diameter of 130-370 kilometers (nominally 160) which puts it on a similar scale, if not larger than, Sarabat's huge comet C/1729 P1, and almost undoubtedly the largest Oort Cloud object ever discovered- almost in dwarf planet territory! i have little doubt in my mind that as this gets closer to the sun, it will begin displaying the coma and tail typical of every other object yet seen in its orbit.

Geologists on the New Horizons team combined images of Pluto’s surface to make 3-D maps that indicate two of Pluto’s most distinctive mountains could be ice volcanoes. In its statement September NASA explained that the ‘ cryovolcanoes ’ may even have been active in the recent past. The two candidates are large features on the dwarf planet’s surface measuring tens of miles across and several miles high. Related : September NASA releases first Pluto flyby images.
