Anyway, all speak Italian, almost all Roman native do speak Roman, I'd say 30% English (good or awful), mainly older people may know (remember) Latin, not necause they're *so* old :) but because nowadays Latin is taught in secondary school only, and just some (Liceo).
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.
The diameter of Pluto is only 2,390 km across. Just for comparison, thatâs about 70% the diameter of the Moon. And itâs a fraction of the size of the Earth; about 18% of the Earthâs diameter. In terms of volume, Pluto only has 6.39 x 10 9 km 3.
