Cat's Eye Nebula Diameter

In NGC 40we detect faint diffuse X-ray emission distributed within a partialannulus that lies nested within a 40 diameter ring of nebulosityobserved in optical and near-infrared images. 3000 light-years 1000 parsecs Dimensions. This image is 12 arcminutes 12 light-years or 035 parsecs wide.

Cat S Eye Nebula

Concentric rings reveal episodic mass loss.

Cat's eye nebula diameter. It would take a space ship 50000 years travelling at the speed of light to get from one side to the other. The nebulas core has an apparent size of 20 and a high surface brightness. Our galaxy has a span of 100000 light years.

The Cats Eye Nebula is 3x10 to the power of 16 meters in diameter. 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. This nebula possesses a very vast halo of matter ejected during its phase of red giant.

Discovered by Karl Ludwig Harding probably before 1824 this object is one of the closest to the Earth of all the bright planetary nebulae. 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. The star in the white dwarf stage is clearly visible in the center of the nebula the central part of which has a diameter of only 20 arc seconds which is tiny one of the reasons why it is relatively little imagined.

Seeing varys between 3-22 FWHM. 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. What is an example of a planetary nebula.

Cats Eye Nebula has a radius of 25000 light years or to put it another way it has a diameter of 50000 light years. Cats Eye Nebula NGC 6543 is a planetary nebula. The Cats Eye Nebula.

Hen 2-99 is not detectedThe inferred X-ray temperature TX106 K andluminosity LX21030 ergs s-1of NGC 40 are the lowest measured thus far for any PN displaying diffuseX-ray emission. No two look alike. This nebula possesses a very vast halo of matter ejected during its phase of red giant.
