PSR J0002+6216, also dubbed the Cannonball Pulsar, is a pulsar discovered by the Einstein@Home project in 2017.[2] 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[3]), 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.[4] 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.[5][4] There is bow-shock pulsar wind nebula (PWN) associated with PSR J0002+6216. [6]
