Black Hole with an orbiting body describing a rosette
Black Hole with an orbiting body describing a rosette. The simulation begins with a body (or satellite, shown as a yellow ball) with a certain velocity that is tangential to a Black Hole (shown as a bluish body in the centre). The resulting orbit creates a flower-like pattern or rosette. Notice how the object speeds up as it approaches the singularity. This is shown by the tracer balls being more widely spaced. Once the movie has fully appeared you can move the slider back and forth to see these effects at different speeds. Rosette or rose shaped orbits occur when a body (red sphere) orbits around an attractor (yellow sphere) and the force pulling the body to the attractor is inversely proportional to its distance from the attractor (proportional to 1/r). Because the force gets stronger the closer the body gets, it speeds up as it approaches the attractor (the pink tracer dots are further apart near the attractor).
