Now, a one-of-a-kind survey has revealed a total of 74 other similar belts surrounding planetary systems close to our own. We have actually seen this process taking place in other planetary systems beyond our own. A journey in search of other beltsAt first glance, finding exocomet belts should be easy given how large they are. The survey contains images of 74 belts around “nearby” planetary systems found within 500 light-years from us. As we get to know more about exocomet belts, we may finally be able to understand the role that belts play in the formation and evolution of planetary systems.
