PSR J0002+6216 explained

PSR J0002+6216, also dubbed the Cannonball Pulsar, is a pulsar discovered by the Einstein@Home project in 2017.^[1] It is one of the fastest moving pulsars known, and has moved 53ly 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 1127km/s, it is leaving a 13ly long wake tail and is traveling fast enough to leave the Milky Way galaxy. The pulsar is currently 6500ly away in the Cassiopeia constellation. The star rotates at a rate of 8.7 times a second.^{[3] [4]} There is bow-shock pulsar wind nebula (PWN) associated with PSR J0002+6216. ^[5]
