18 mar 2016 · Pluto's small size and low mass mean that it has a density of 1.86 grams per cubic centimeter according to recent measurements by New Horizons, about 40 percent of Earth's density.
15 paź 2024 · When these characteristics are combined with what is known about its density and composition, Pluto appears to have more in common with the large icy moons of the outer planets than with any of the planets themselves.
Because of the orbital interactions between Pluto and its moon Charon, Pluto’s mass is well known and understood (1.31 x 1022 kg). Having a more precise diameter gives scientists the ability to more accurately calculate Pluto’s average density.
The mass of Pluto is less than .024 percent than that of earth (1.31×10_22 kg). That is roughly seven times (.0021) the mass of Earth. Its diameter is 2,390 km, which is relatively smaller than that of the Earth’s moon. The density on Pluto ranges from 1.8 to 2.1 grams per centimeter cubed.
Pluto's density is 1.87 g/cm 3. [29] Because the decay of radioactive elements would eventually heat the ices enough for the rock to separate from them, scientists think that Pluto's internal structure is differentiated, with the rocky material having settled into a dense core surrounded by a mantle of water ice. [ 30 ]
18 lip 2015 · With a mean density of 1.87 g/cm3, Pluto’s composition is differentiated between an icy mantle and a rocky core. The surface is composed of more than 98% nitrogen ice, with traces of...
