About this image

This small (0.86') planetary nebula was discovered by William Herschel in 1787. It is unusual in that the central star pulsates rapidly creating rapid variations in the nebula's brightness.

The name Camel Eye Nebula seems erroneous given that Camelopardalis means Giraffe. But the name originates from the combination of the Greek kamēlos = camel and pardalis = leopard, giving camel-leopard. The giraffe was seen to resemble a camel with its long neck and a leopard with its spotted coat.

Distance c.4,240ly.
