Pluto-Charon Eclipse (2010)
Pluto and Charon are so oriented that, twice every orbit (once every 124 years), they
periodically eclipse each other as each world passes between the Sun and its partner.
This movie shows the process. The last time Pluto and Charon eclipsed each other was
during the six-year interval from 1985 to 1990. It won't happen again until 2103. The
movie also shows Hydra and Nix, Pluto's two smaller moons, which were discovered
using the Hubble Space Telescope in 2005.
