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.
4 paź 2021 · The rate at which the star disappeared and reappeared determined the density profile of Pluto’s atmosphere.
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.
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.
