Collisions between bodies in our Solar System produce impact craters on large objects at a rate that depends on the population of impacting small bodies. By mapping the scars of ancient impacts on the surfaces of Pluto and its moon Charon, planetary researchers have discovered a surprising lack of very small objects (from 300 feet to 1 mile, or 91 m to 1.6 km, in diameter) in the Kuiper Belt.

The largest of Pluto’s five moons, Charon, was discovered 40 years ago today by James Christy and Robert Harrington at the U.S. Naval Observatory in Flagstaff, Arizona – only about six miles from where Pluto itself was discovered at Lowell Observatory. They weren’t even looking for satellites of Pluto – Christy was trying to refine Pluto’s orbit around the Sun.
