 Other examples of natural bodies known to be in horseshoe orbits (with respect to each other) include Janus and Epimetheus, natural satellites of Saturn.The orbits these two moons follow around Saturn are much simpler than the one Cruithne follows, but operate along the same general principles.Mars has four known co-orbital asteroids (5261 Eureka, , , and , all at the Lagrangian points), and Jupiter has many (an estimated one million greater than 1 km in diameter, the Jovian trojans); there are also other small co-orbital moons in the Saturnian system
