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.
Having a more precise diameter gives scientists the ability to more accurately calculate Pluto’s average density. This is important information for scientists because it helps them understand the composition of Pluto. 1. Find the radius(r) of Pluto. 2,370 kilometers ÷ 2 = 1,185 km. 2. Find the circumference of Pluto. C = 2 π r = 7,446 km. 3.
Pluto is about two-thirds the diameter of Earth's Moon and probably has a rocky core surrounded by a mantle of water ice. Interesting ices like methane and nitrogen frost coat the surface. Due to its lower density, Pluto's mass is about one-sixth that of Earth's Moon. Surface. Surface
28 wrz 2017 · These maps are from NASA's New Horizons' data on the topography (top) and composition (bottom) of Pluto's surface. In the high-resolution topographical map, the highlighted red region is high in elevation.
21 gru 2009 · Pluto is no longer a planet, but a dwarf planet. Mass: 0.0125 x 10 24 kg. Volume: 0.715 x 10 10 km 3. Average radius: 1,195 km. Average diameter: 2,390 km. Mean density: 1.750 g/cm 3....
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.
