'''Nemesis''' is a theoretical [[dwarf star]] said to orbit the sun outside of the [[Oort Cloud]]. Some scientists believe that if Nemesis exists, it's passing by the [[Oort Cloud]] might send asteroids towards Earth. This hypothesis is sometimes used to back up the belief that the dinosaurs were killed by a large asteroid or meteor impact.
