Double Transit

(star showing transits of two bodies)

A Double Transit is a stellar phenomena suggesting two bodies transiting the star, i.e., evidence of a system with at least two Extra-Solar Planets. The Transits may overlap, suggesting a Moon or a very lucky find of planets in resonance.

An alternate way of detecting multi-planet systems is Transit Timing Variationses.
