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.
Planetary scientists have calculated Plutoâs density at between 1.8 and 2.1 g/cm 3. From this density, they have calculated that its interior is probably 50-70% rock and 30-50% ice. Decaying radioactive elements inside Pluto would heat the interior of the dwarf planet, allowing the rock and ice to move around.ut NASAâs New Horizons spacecraft is making the journey to Pluto, and will make a flyby in 2015. At that point, it will fly within 10,000 km of Plutoâs surface and send back images that show features as small as 1.6 km across.
