Path of the shadow of the dwarf planet Eris during the occultation of November 2010 (artist's impression)

This artist’s impression shows the shadow of the dwarf planet Eris as it was crossing the Earth during the occultation during November 2010. The regions along the path saw a faint star briefly disappear as its light was blocked by Eris. Studies of where the event was seen, and for how long, have allowed astronomers to measure the size of Eris accurately for the first time. Surprisingly, they find it to be almost exactly the same size as Pluto and that it has a very reflective surface.
