Atmosphere Mass

The Atmosphere Mass property of an object represents the total mass of its atmosphere.

Property Details

Location

The Atmosphere Mass property is located in the Atmosphere section of the Surface tab of the object's properties panel. This section is only visible for Terrestrial Planets.

Units

Atmosphere Mass can be viewed and edited using the following units:

• Earth atmosphere mass (earth atm) = 5.148×10¹⁸ kg
• Mars atmosphere mass (mars atm) = 2.50×10¹⁶ kg
• Kilogram (kg) is the SI base unit for mass
• Grams (g) = 0.001 kg
• Milligrams (mg) = 10^-6 kg

Simulation Effects

Surface Pressure

The Atmosphere Mass is related to the surface pressure, P, and radius of the object, R, and the gravitational constant, G, by the following equation:

$M_{atmo}={\frac {4\pi R^{2}P}{G}}.$
