New Horizons Now Closer to Pluto than Earth is to the Sun

At around 5:20 p.m. EDT on March 10th, NASA’s New Horizons spacecraft crossed the one Astronomical Unit from Pluto distance marker. An Astronomical Unit or AU, is the average distance between the Earth and the Sun, about 149 million kilometers or 93 million miles.

Pluto is a small, mysterious world, deep in the cold, dark recesses of the distant outer solar system. We’ve been waiting for a long time to see it. Finally, we are almost there.
