The Density of an object is its mass per unit volume. All objects in Universe Sandbox are assumed to have uniform density.

Property Details[]

Location[]

The Density property of an object can be found near the top of the Overview panel in the object's property panel. If the object has a Composition tab, the Density will also be listed under the Cumulative Properties category in that tab. For a Galaxy Nebula object, the Density property is located near the top of the Nebula tab.

The Density of an object is also displayed in its mini-info panel.

Units[]

Density can be viewed and edited using the following units:

  • Grams per cubic centimeter (g/cm3) = 1000 kg/m3
  • Kilograms per cubic meter (kg/m3) is the SI base unit for density
  • Hydrogen molecules per cubic centimeters (H2/cm3) = 1.67×10-24 kg/m3

Simulation Effect[]

Mass and Radius[]

Objects in Universe Sandbox are simulated as spheres of uniform density, so the density of an object, ρ, is related to its radius, R, and mass, M, by
