FRB 180916, also known as FRB 180916.J0158+65, is a distant extragalactic repeating fast radio burst source about 486,000,000 light-years away in the constellation Cassiopeia. In 2018, the FRB was detected and localized in the galaxy SDSS J015800.28+654253.0. In 2021, a study suggested that the repeating bursts could be explained by a magnetar interacting with a 2.87 Earth mass planet in a highly eccentric orbit, with an orbital period of 16.25 days to explain the periodicity. which the possible planet is yet to be confirmed.

There are other explanations for this repeating FRB source, such as a high mass X-ray binary system consisting of a magnetar passing through the dense wind of a blue supergiant companion. For now, these hypotheses are not yet proven to be the progenitor of FRB 180916.
