   Planet
   Any large body orbiting a star. A somewhat arbitrary term since there appears to be no defining size that clearly differentiates between a planet or asteriod. For example, Pluto is widely regarded as the ninth planet of the Solar System yet its parameters do not clearly conform to the other eight planets of the Solar System. Although it seems unlikely to lose its planetary status, Pluto does appear to be an oddity when you consider such things as its orbit, size and other known data.
