Orbit can simultaneously have up to 10 satellites (station, entity, and moon).
As soon as a new object appears in orbit, the collision probability is calculated.
The chance of a collision is equal to the square of the number (the new object does not count). 10 objects are 10 * 10 = 100%
Stopping of the entity (not jumping), teleporting of the station, generating of a new moon is the appearance of a new object.
If there are already 7 satellites in orbit, they will never collide.
An arriving satellite and one of the standing can collide randomly.
The gravitational field of two satellites is mutually subtracted, with the destruction of one or both during collision.
