"The Crab Nebula is a supernova remnant in the constellation of Taurus.
The nebula lies in the Perseus Arm of the Milky Way galaxy, at a distance of about 2.0 kiloparsecs (6,500 ly) from Earth. It has a diameter of 3.4 parsecs (11 ly) and is expanding at a rate of about 1,500 kilometres per second or 0.5% of the speed of light."
