D09.3.1._Reclassification of Pluto
RECLASSIFICATION OF PLUTO
Discovered in 1930, Pluto was considered the ninth and most distant planet of our Solar System for more than 70 years. However, after discovering objects of similar size, its status as a planet was widely questioned. Members of the IAU who gathered at the 26th General Assembly in 2006 in Prague (Czech Republic) agreed on a new definition of planet: an object that is in orbit around the Sun, has a spherical shape and has cleared the neighbourhood around its orbit. As a consequence, this resolution reclassified Pluto as a dwarf planet. The discussion around redefinition has attracted much interest and triggered discussions among the scientific community and the general public alike.
