Eleventh planet term "planet" was redefined to exclude the new category of dwarf planets (just as some planets had earlier been recategorised as asteroids). In 2006 Pluto, Eris, Haumea, Makemake, and (in the inner Solar System) the asteroid Ceres were reclassified as dwarf planets. Eleventh planet Eleventh planet (of the Solar System) may refer to Vesta, the eleventh object to be named a planet, later to be reclassified as an asteroid; Uranus, the eleventh planet from the Sun upon Vesta's discovery, though this was quickly superseded by new discoveries; or Haumea, which would be the eleventh planet if the classification advocated by
European Solar Telescope visible and near-infrared instruments simultaneously, thereby improving photon efficiency and diagnostic capabilities relative to other existing or proposed ground-based or space-borne solar telescopes. In May 2011 EST was at the end of its conceptual design study. The EST is being developed by the European Association for Solar Telescopes (EAST), which was set up to ensure the continuation of solar physics within the European community. Its main goal is to develop, construct and operate the EST. The European Solar Telescope is often regarded as the counterpart of the American Daniel K. Inouye Solar Telescope which is currently being constructed. The conceptual
