So, mercury is a little less than 8 times the size of pluto, in terms of volume. (If mercury and pluto were water tanks, mercury would hold a little less than the water 8 plutos can hold) Surface area of pluto = 16245414 km^2 Surface area of mercury = 63053021 km^2 So, mercury is almost 4 times pluto, in terms of surface area. read more
