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.
11 sty 2024 · Pluto Atmosphere Surface Pressure: ~13 microbar Surface temperature: 24 - 38 K (-247 - -233 C) Scale height: ~18 km lower atmosphere, ~50 km above 30 km Mean molecular weight: ~28 Atmospheric composition: 99% Nitrogen (N 2), 0.5% Methane (CH 4), 0.05% Carbon Monoxide (CO), trace HCN, C 2 H x hydrocarbons
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?
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 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
15 wrz 1988 · The mean density of the Pluto-Charon system is now accurately known at 1.99±0.09 g cm–3 (With formal errors five times smaller)1, through observations of total occultations and transits2.
11 lip 2021 · Report the density in g/cm3, without entering units. Calculate the average density of planet Pluto, given its mean distance from the sun is 5. 91×109 km, its radius is 1137 km, its volume is 6. 157×109 km3, its orbital period is 248. 1 years and its mass is 1. 25×1022 kg.
