Astronomy/Astrophysics - Eris: Queen of the Dwarf Planets

Apart from all the planets in the solar system, we've discussed smaller objects as well, like asteroids and comets, and also dwarf planets. While Pluto is the most famous dwarf planet, Eris is actually slightly more massive, making it the most massive object in the solar system after the sun and the planets. But it is very, very far away, much farther than Pluto, so how do we get information about this object? We calculated its size in 2010 by observing a phenomenon called stellar occultation. This is a fascinating technique, so let's get a closer look now.
