File:Fomalhaut b orbit animated (2004-2012).webm

English: The Fomalhaut system harbors a large ring of rocky debris that is analogous to our Kuiper belt. Inside this ring, the planet Fomalhaut b is on a trajectory that will cause it to pass straight through the ring. The nature of the planet remains mysterious, with the leading theory being the planet is enveloped in a sphere of dust. The footage uses 5 images taken over 7 years using the Hubble Space Telescope. The ring is so large we don't have enough coverage of the ring to animate it. Rather, it is a composite image that combines all the data on the ring.
