periodic orbits for 3 body
These images show some newly discovered periodic (repeating) orbits for 3 and 4 bodies.

Caption A: Three bodies with equal mass orbiting on a figure eight. This result was published in 2000.

Caption B: Three bodies of unequal mass. This system is similar to a planet orbiting a binary star system.

Caption C: Two pairs of bodies orbiting about each other.

Caption D: An orbit discovered in 2008 by Tiancheng Ouyang, Duokui Yan, and Skyler Simmons at BYU.
