FAQ

How do I read the star map?

The center of the circle is the zenith (directly overhead), and the edge is the horizon. North is at the top, South at the bottom, East on the right, West on the left. Hover over a star to see its name and details.

What does the size of a star mean?

The size of a star represents its brightness (magnitude). A lower magnitude number means a brighter star. Sirius at magnitude -1.46 is the brightest, while magnitude 6 stars are barely visible to the naked eye.

When can I see the most stars?

On a clear moonless night, far from city lights, you can see the most stars. In Korea, the Milky Way is also visible in summer (July–August).

What are constellation lines?

Constellation lines connect stars to show constellation patterns. They don't exist in the real sky but help you understand constellation shapes.
