If you count a dwarf planet, then yes: Eris was discovered in 2003 (but not identified until 2005). It is currently three times further from the sun than Pluto. Eris is larger than Pluto, and before the term "dwarf planet" was officially adopted in 2006, it was suggested that Eris had to be considered the solar system's tenth planet. If you don't count dwarf planets, then we actually lost a planet since the year 2000: In 2006, Pluto was downgraded from a planet to a "dwarf planet". In the year 2000 our solar system officially had nine planets, now it has eight. But it has three dwarf planets (Eris, Pluto, and Ceres).
