Why Map Light Pollution?
Artificial light glow ("skyglow") washes out 90% of visible stars in urban areas. Our tool uses satellite data to calculate the Bortle Scale rating of your location, helping you find the nearest sanctuary where the Milky Way is visible to the naked eye.
The Bortle Scale
We grade skies from Class 1 (Ancient Dark Skies) to Class 9 (Inner-City Sky). Serious astronomy begins at Class 4. Use SkyNearMe to plan your next camping trip or telescope session in a certified Dark Sky Park.
