Note:
The international Astronomical Union (IAU) has dropped Pluto from the list
of nine planets in the solar system. This decision was made at the IAU
General Assembly held in August 2006. According to the IAU, the present
solar system consists of eight planets only. As a result Pluto has been moved
to the status of a dwarf planet. Pluto, Ceres, Eris, Makenake & Haunea are
the first five recognised dwarf planets in the solar system.
