    • Hodgins: Pluto's no longer a planet. It was demoted.

      Pluto was discovered in 1930, but on August 24th, 2006, the International Astronomical Union members' meeting in Prague demoted it to a secondary category of dwarf planet. The new qualifications for a celestial body in our Solar System to qualify as a planet are: 1) It must be in orbit around the Sun, 2) It must be large enough that it takes on a nearly round shape 3) It has cleared its orbit of other objects.

      Pluto was automatically disqualified because its highly elliptical orbit overlaps with that of Neptune.
