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.
The average density of planets in order are:- Earth, Mercury, Venus, Mars, Neptune, Jupiter, Uranus, and Saturn. For reference (1 gm/cm3 = 1000 kg/m3). The density of water is almost 1 gm/cm3 or 997 kg/m3. The Density of Dwarf Planets. Below, you can find the density of five dwarf planets.
Alan Stern has contended that even a small increase in Pluto's surface temperature can lead to exponential increases in Pluto's atmospheric density; from 18 hPa to as much as 280 hPa (three times that of Mars to a quarter that of the Earth). At such densities, nitrogen could flow across the surface as liquid. [137]
From an average distance of about 3.7 billion miles (5.9 billion kilometers), Pluto is about 39 times farther away than the Earth is from the Sun. From this distance, it takes sunlight 5.5 hours to travel from the Sun to Pluto.
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.
But on average, Pluto is 3.7 billion miles (5.9 billion kilometers) away from the Sun, or 39 AU. From 1979 to 1999, Pluto was near perihelion, when it is closest to the Sun. During this time, Pluto was actually closer to the Sun than Neptune. One day on Pluto takes about 153 hours.
1 paź 2024 · The outer or uppermost part of a planet, moon, asteroid, comet or other body. The gravitational acceleration experienced at its surface at the equator. The speed needed for an object to break away from the gravitational pull of a planet or moon. The numbers displayed here are approximations.
