10:01Now PlayingTRAPPIST-1 is an amazing system discovered last year featuring seven roughly Earth-sized planets all transiting their diminutive parent star. Could there be an eighth? If there is, in this video Prof Kipping argues that it should be possible to precisely predict what the orbital period of such a planet would be. Right or wrong, this prediction provides a falsifiable hypothesis to test our understanding of the rules governing planetary system architectures.
