Planets and plutons

Are we soon to expand our solar sytem to include more planets?

Mercury, Venus, Earth, Mars, Ceres, Jupiter, Saturn, Uranus, Neptune, Pluto, Charon and 2003 UB313 ?

Ceres orbits in teh asteroid belt, Charon was a moon of Pluto but now Pluto and Charon are two planets (or plutons) orbiting each other. 2003 UB313 (provisional name – thank goodness!) is one further out even than pluto, but thought to be much bigger.

Any suggestions for 2003 UB313 – your comments / suggestions welcome.

  1. Answer: No!

    In fact our solar system has shrunk. (Figuratively that is – it can’t really change of course, only how we define it)

    So Pluto has now been reclassed as a dwarf planet but gets the impressive “Double dwarf planet” title with its companion Charon.
