A Galaxy object is made up of several Galaxy Nebula objects and a single Black Hole (see Galaxy Structure). A Black Hole in a Galaxy will exert a gravitational force on other objects in the simulation based on the total mass of the galaxy, rather than the mass of the Black Hole itself.
The properties panel for a Black Hole object will include the following tabs:
Black Hole objects have the following sets of properties:
- They are attracting objects, meaning that they 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 can be displayed.
- They can collide with other objects.
- They have a simulated composition.
