The Crab Nebula is a supernova remnant and pulsar wind nebula in the constellation of Taurus.
Corresponding to a bright supernova recorded by Chinese astronomers in 1054, the nebula was observed later by John Bevis in 1731.
It has an apparent magnitude of 8.4.
Located at a distance of about 6,500 light-years from Earth, the nebula has a diameter of 11 light years ( corresponding to an apparent diameter of some 7 arc minutes) and expands at a rate of about 1,500 kilometers per second (WIKI)
