This page shows Pluto location and other relevant astronomical data in real time. The celestial coordinates, magnitude, distances and speed are updated in real time and are computed using high quality data sets provided by the JPL Horizons ephemeris service (see acknowledgements for details).
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.
The rate at which the star disappeared and reappeared determined the density profile of Pluto's atmosphere. "Scientists have used occultations to monitor changes in Pluto's atmosphere since...
13 lip 2015 · Pluto’s newly estimated size means that its density is slightly lower than previously thought, and the fraction of ice in its interior is slightly higher. Also, the lowest layer of Pluto’s atmosphere, called the troposphere, is shallower than previously believed.
Mean Density: Density computed using the volume of a sphere with the specified mean radius and mass (derived from GM) of the planet.
