New Horizons: Pluto

[MichaelPoole]

Interesting: for all the tumultuous terrain, there's not a lot of craters on Pluto or Charon. Those are very young surfaces.

If you say so. I had been wondering what the incidence of cratering per millennium way the heck out there was and thinking that our inner-system standards for judging age by craters might not be accurate.

The moons of Uranus and Neptune are all very cratered, save for those geologically active (like Triton).
