On Pluto's New Moons

Pluto, that distant planet at the edge of the solar system, so far that the Sun appears as little more than an ordinary star, has been revealed to have two new moons, in addition to the previously discovered Charon.

[U]sing images from the Hubble Space Telescope, scientists from Johns Hopkins University, Southwest Research Institute and the Massachussetts Institute of Technology say they have found two more tiny orbiting satellites, P1 and P2.

Both are traveling outside the orbit of Charon and are tiny by comparison, the scientists wrote in the journal Nature.

We learn something new every day. I wonder what the Pluto Express will make of this. 🙂
