Great Comet
The Kreutz Sungrazers consist of two major subgroups, which are descended from further breakups of two different fragments of the original comet. Studies have shown that Pereyra is a member of the subgroup which includes the Great Comet of 1843 and the Great Comet of 1882, although the separation of Pereyra from the larger fragment probably occurred one orbit before the two Great Comets separated.
