Universe Sandbox Wiki

A Galaxy Nebula in Universe Sandbox is a simulated object representing a cloud of gas, dust, and stars in a galaxy.

Properties Panel[]

The properties panel for a Galaxy Nebula object will include only a Nebula tab.


Galaxy Nebula objects have the following characteristics:

  • They are non-attracting objects, meaning that they do not exert a gravitational force on other objects in the simulation.
  • They are attracted objects, meaning that they feel the effects of gravity from other attracting objects in the simulation.
  • They have calculated orbital elements, and their orbit may be displayed.
  • They do not collide with other objects, instead passing right through them.
  • They experience nebula evolution, in which their nebula-specific properties evolve with time according to their position within the galaxy.
