The following video features 10 hours of a NASA recording of the dwarf planet Pluto. It is now considered a dwarf planet, but it will always be a planet in m...
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.
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.
From the diameter and mass, we find a density of 1.9 g/cm 3, suggesting that Pluto is a mixture of rocky materials and water ice in about the same proportions as many outer-planet moons. Parts of Pluto’s surface are highly reflective, and its spectrum demonstrates the presence on its surface of frozen methane, carbon monoxide, and nitrogen.
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.
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.
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.
