PSR J0002+6216, also dubbed the Cannonball Pulsar, is a pulsar discovered by the Einstein@Home project in 2017. It is one of the fastest moving pulsars known, and has moved 53 ly (5.0×1014 km; 3.1×1014 mi) away from the location of its formation supernova, where the remaining supernova nebula, CTB 1 (Abell 85[2]), is. Due to its speed in traversing the interstellar medium, at 1,127 km/s (700 mi/s), it is leaving a 13 ly (1.2×1014 km; 7.6×1013 mi) long wake tail and is traveling fast enough to leave the Milky Way galaxy.[3] The pulsar is currently 6,500 ly (6.1×1016 km; 3.8×1016 mi) away in the Cassiopeia constellation. The star rotates at a rate of 8.7 times a second.[4][3]
