#Orbital motion - there are exotic possibilities such as knife-edge #orbits, in which the #satellite can be made to execute an arbitrarily large number of nearly circular orbits, after which it flies back outward. https://en.wikipedia.org/wiki/Schwarzschild_metric#Orbital_motion
In #Einstein's theory of general #relativity, the #Schwarzschild solution is an exact solution to the Einstein field equations that describes the #gravitational field outside a spherical mass

Wow. When printed out to original size, the black circle on this diagram is the exact size of a #blackhole of size 5 #earth masses!
