In the early 23rd century Pluto will switch ranking with Neptune and temporarily, for about 20 years, will become the 8th planet from the sun. The last time this occurred was during 1979-1999.
Based upon current orbital calculations which gives it a year equivalent to 286 Earth years, in 2288, the planetoid 50000 Quaoar will have completed one complete orbit of the sun since its discovery in 2002.

It was originally named Traveller 2300, but the back story of 2300 AD is very different from the Traveller universe and the game was therefore renamed in its 2nd edition.
2300 AD is set at the dawn of the 24th century (between 2298 and 2301 depending on the book or supplement).
The background story of 2300 AD is based on the nuclear war depicted in the Twilight 2000 role-playing game by the same company.
