Although visible eye stars can go to 65 in magnitude the dimmest star for this will be a 60. Discovered by Karl Ludwig Harding probably before 1824 this object is one of the closest to the Earth of all the bright planetary nebulae. The Cats Eye Nebula is 3x10 to the power of 16 meters in diameter.
This composite of data from NASAs Chandra X-ray Observatory and Hubble Space Telescope gives astronomers a new look for NGC 6543 better known as the Cats Eye Nebula. No two look alike. The Catss Eye Nebula is a perfect example of a planetary nebula.
This composite image with Hubble Space Telescope data red and green shows where the hot X-ray emitting gas appears in relation to the cooler material seen in optical wavelengths. The nebula formally cataloged NGC 6543 is every bit as inscrutable as the JRR. 3000 light-years 1000 parsecs Dimensions.
