NGC 6543 facts for kids
NGC 6543 is a beautiful object found far away in space. It is known as a planetary nebula. This amazing cloud of gas and dust is located in the Draco constellation. Draco is a group of stars that looks like a dragon in the night sky. NGC 6543 is quite far away from Earth. It is about 3,300 light-years from us!

What is a Planetary Nebula?
A planetary nebula is not a planet at all! It is a huge cloud of gas and dust. These clouds form when a star like our Sun reaches the end of its life. As the star runs out of fuel, it swells up into a red giant. Then, it sheds its outer layers of gas into space. This creates a colorful, expanding shell. The hot core of the star, now called a white dwarf, shines brightly. Its light makes the gas glow. This glowing gas forms the beautiful shapes we see.
Why is it called a "Planetary" Nebula?
Early astronomers, like William Herschel, first saw these objects through their telescopes. They looked round and fuzzy, a bit like planets. That is why they were called "planetary" nebulae. We now know they have nothing to do with planets. They are actually the last stage of a star's life.
Where is NGC 6543 Located?
NGC 6543 is found in the northern sky. It is part of the Draco constellation. This constellation is named after a dragon. You can see Draco winding its way around the North Star. Finding NGC 6543 requires a good telescope. It is a small but bright object.
How Far Away is it?
This nebula is about 3,300 light-years from Earth. A light-year is the distance light travels in one year. Light moves incredibly fast, about 186,000 miles (300,000 kilometers) per second! So, 3,300 light-years is a truly huge distance. The light we see from NGC 6543 today left the nebula 3,300 years ago.
Who Discovered NGC 6543?
NGC 6543 was discovered by a famous astronomer. His name was William Herschel. He found it on February 15, 1786. William Herschel was a very important figure in astronomy. He also discovered the planet Uranus! He spent many hours looking at the sky. He used powerful telescopes that he built himself.
What Does NGC Mean?
The "NGC" in NGC 6543 stands for the New General Catalogue. This is a list of deep-sky objects. These objects include nebulae, galaxies, and star clusters. The catalogue was put together by John Louis Emil Dreyer in 1888. It lists thousands of objects that astronomers have found.
