Cheonsang Yeolchabunyajido is a map that shows all the stars in the night sky. Imagine looking up at the stars in the sky and seeing so many of them that you can't keep track of them all. This map helps you keep track of all the stars and their patterns so that you can find your way around the night sky.
The map is divided into different sections, just like a puzzle. Each section shows a different part of the sky, like a patch of it. The different sections are put together to make a complete map of the sky.
The stars on the map are not just any stars, they are the ones that are visible to us from Earth. Scientists studied the sky and made a list of all the stars that we can see called the "stellar catalog." This catalog is used to create the map, so all the stars you see on the map are real stars!
Each star on the map has a special name, like how your friends have names. The stars' names are made up of numbers and letters which can be confusing, but it helps astronomers identify them.
Overall, this map was created to help people navigate the night sky and understand more about the stars we can see. With the cheonsang yeolchabunyajido, you can find your favorite constellations, watch out for shooting stars, and even spot a planet or two!
