Find Your Pluto Time

Dwarf planet Pluto with a heart-shaped feature showing.

Pluto orbits on the fringes of our solar system, billions of miles away. Sunlight is much weaker there than it is here on Earth, yet it isn't completely dark. In fact, for just a moment near dawn and dusk each day, the illumination on Earth matches that of high noon on Pluto.

We call this Pluto Time.

If you go outside at this time on a clear day, the world around you will be as bright as the brightest part of the day on Pluto.
