In 2006 Pluto was announced to be a dwarf planet because it did not meet the proper criteria for being a planet. International Astronomical Union (IAU) states that in the Solar System a planet is a celestial body that:
1. is in orbit around the Sun,
2. has sufficient mass to assume hydrostatic equilibrium (a nearly round shape), and
3. has "cleared the neighborhood" around its orbit.
Since Pluto does not meet the 3rd planet requirement it was deemed a dwarf planet. Since then the IAU has discovered a new and larger dwarf planet named Eris. Do you feel that it is necessary to classify Pluto as a dwarf planet for sake of science? OR Should we reclassify it as a planet for the sake of tradition? Please explain answer thoroughly and choose one definitive side.
