Pluto’s Moons and Planetary Status

Wednesday, June 28th, 2006 at 01:26 PM

The composition of Pluto is similar to those of comets, which lie outside of Neptune’s orbit.The object 2003 UB313, or also known as Xena, will also be looked at closely to be determined if it is a planet or not. 2003 UB 313 is slightly larger than Pluto, is further out than Pluto, and has a greater inclination to the ecliptic (44 degrees).In August this summer, the IAU will give a definition of a planet and will decide if Pluto or Xena fit the definition.
