Animation: 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.
