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.
Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of bodies beyond Neptune.It was the first Kuiper belt object to be discovered.t is less massive than the dwarf planet Eris, a trans-Neptunian object discovered in 2005, though Pluto has a larger diameter of 2372 km compared to Eris's approximate diameter of 2326 km. Determinations of Pluto's size had been complicated by its atmosphere, and possible hydrocarbon haze.
