The rings of Earth are a proposed set of planetary rings that may have at one point been present around Earth during the Ordovician period. These rings may have formed during the Ordovician impact spike approximately 466 million years ago.[1][2][3] They were first formally proposed by a team of scientists working with the Monash University in September 2024, and have been a subject of interest for several years prior to the study.
