Universe Sandbox Wiki

The Stellar Power property of an object represents the rate that energy from stellar heating is absorbed by the object over time. Stellar Power is a read-only property that is continually calculated by Universe Sandbox.

Property Details[]


For Planetary Body object, the Stellar Power property is located in the Energy Flow section of the object's Surface tab, when the Energy Absorption Rate property is expanded. For Stars, Black Holes, Fragments, and Human-Scale Objects, the Stellar Power property is located in the Temperature tab.


Stellar Power can be viewed using the following units:

  • Solar luminosity (L star) = 3.846×1026 W
  • Watts (W) is the SI unit for luminosity.

Simulation Effects[]


Stellar Power is one of several sources of energy that can increase an object's Average Temperature or Surface Temperature.
