Pluto's diameter is 2372 km and its mass is 1.31Ã10 22 kg, which is less than 17.82% of the Moon (less than 0.24% of Earth). Its surface area is 7013166500000000000â 1.665Ã107 km2, or roughly the same surface area as Russia.n 1978, the discovery of Pluto's moon Charon allowed the measurement of Pluto's mass for the first time: roughly 0.2% that of Earth, and far too small to account for the discrepancies in the orbit of Uranus. Subsequent searches for an alternative Planet X, notably by Robert Sutton Harrington, failed.
