Its Age Is Estimated At Around 1000 Years And Its Distance At 3000 To 3600 Light Years.
The nebula, formally cataloged ngc 6543, is every bit as inscrutable as the j.r.r. As the fuel runs low, the innermost regions of the star will contract due to the weight of the overlying stellar material. 17h 58m 33.4s declination + 66 ° 37 ′ 59 ″ appearance apparent brightness (visual) 8.1 likes
Estimated To Be 1,000 Years Old, The Nebula Is A Visual.
Because of its appearance, ngc 6543 was named the cat's eye nebula. Planetary nebulae are like snowflakes: The size and expansion rate of the cat’s eye suggest the nebula is just 1,000 years old.
(Our Galaxy Has A Span Of 100,000 Light.
The nebula’s designation in the new general catalogue is ngc 6543. The eyes of the cat are large in relation to the skull and provide him with a wider field of vision than that of humans ( 295 degrees compared to our 210. 3.3 ± 0.9 kly (1.0 ± 0.3 kpc) [2] apparent magnitude (v) 9.8b [1] apparent dimensions (v) core:.
While The Planetary Nebula Phase Is Thought To Last For Around 10,000 Years, Astronomers Estimate The Age Of The Outer Filamentary Portions Of This Halo To Be 50,000 To 90,000 Years.
The cat’s eye is one of the most structurally complex nebulae known. It is estimated to be 1,000 years old. The stated age of astronomical objects almost never refers to their actual age.
La Nébuleuse De L’œil De Chat (Ngc 6543) Est Une Nébuleuse Planétaire Située Dans La Constellation Du Dragon, Dont L’âge Est Estimé À 1 000 Ans.
The nebula shows the dynamics and late evolution of a dying star. A planetary nebula is the glowing gas ejected during the final stages of evolution of a star similar in mass to our sun. Centered in this stunning image lies eminescu crater on the planet mercury, illuminated by a bright halo of material around its edge.
