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.
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.
Pluto's density is 172 kg/m 3 less than previously thought. Most rock has a density between 2,000-3,000 kg/m3 and ice at very cold temperatures has a density of 927 kg/m 3 . What can we conclude about Pluto’s composition based on the new density measurement?
14 paź 2010 · Answer: We want to match the density of Pluto (1,600 km/m3) by using ice (917 kg/m3) and rock (2300 kg/m3). Suppose we made Pluto out of half-rock and half-ice by mass.
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.

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.
