Pluto wins reprieve but number of planets may rise...
Debate has raged within the scientific community over the status of Pluto for decades.
It intensified in 2003 when astronomers at the Cal Tech discovered UB 313. Nicknamed Xena after the character in the television show, UB 313 is one of more than a dozen celestial bodies in our solar system found to be larger than Pluto.
Under the definition put forward on Wednesday, and subject to ratification by a vote of IAU members on August 24, an object must be in orbit around a star, while not being itself a star.
Secondly, the object must be large enough in mass for its own gravity to pull it into a nearly spherical shape.
Therefore, Pluto would remain a planet, but fall in a newly created category called Plutons, which are distinguished from classical planets in that they reside in orbits around the sun that take longer than 200 years to complete.
Pluto would be joined in this category by two other celestial bodies, Xena and Charon, while another, Ceres, would be known as a dwarf planet.
In all, 12 planets would be listed in our solar system, at least for the time being. -

If the definition is approved by the astronomers gathered at the IAU General Assembly in Prague, our Solar System will consist of 12 planets: Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Charon and 2003 UB313. The three new proposed planets are Ceres, Charon (Pluto's companion) and 2003 UB313.
