Cat's Eye Nebula Diameter
It was discovered by Herschel in 1786.
Cat's eye nebula diameter. Though the Cats Eye Nebula was one of the first planetary nebulae to be discovered it is one of the most complex such nebulae seen in space. Space and Astronomy Image size. Cats Eye Nebula NGC 6543.
Discovered by Karl Ludwig Harding probably before 1824 this object is one of the closest to the Earth of all the bright planetary nebulae. Surrounding the Cats Eye is a huge shell from earlier stellar winds with a diameter of close to 45 light years somewhat larger than the distance from the Sun to Alpha Centauri. The Cats Eye Nebula NGC 6543 is one of the best known planetary nebulae in the sky While there are many images of this object this rendition has captured the extremes of this difficult target.
The distance measured by the Gaia mission is 65513 light-years. The Catss Eye Nebula is a perfect example of a planetary nebula. The Cats Eye Nebula NGC 6543 or of cat eye nebula with a diameter of 20 seconds of bow is situated in the north pole of the ecliptic this very brilliant global nebula is situated in the constellation of the Dragon.
Our galaxy has a span of 100000 light years. The image from Hubbles Advanced Camera for Surveys ACS shows a bulls eye pattern of eleven or even more concentric rings or shells around the Cats Eye. The Cats Eye Nebula is 3x10 to the power of 16 meters indiameter.
Cats Eye Nebula has a radius of 25000 light years or to put it another way it has a diameter of 50000 light years. This nebula possesses a very vast halo of matter ejected during its phase of red giant. Cats Eye Nebula or NGC 6543.
17h 58m 33s42 Dec. It is a Planetary Nebula expanding gas shell ejected from an end-of-life star in the constellation of the Dragon whose age is estimated at only 1000 years and the distance at only 5200 light years. The nebulas core has an apparent size of 20 and a high surface brightness.
