Its official-Pluto's Out

The International Astronomical Union has voted to remove Pluto from the solar system--as a planet, that is.

Meeting in Prague over the past week, IAU members rejected a proposal to increase the number of planets to 12 by including Ceres, the largest known asteroid, which orbits between Mars and Jupiter; Charon, which has been considered Pluto's moon; and 2003 UB313, an object nicknamed "Xena" that was discovered in 2005 orbiting far beyond Pluto.

Pluto is now considered a "dwarf planet" because it has an oblong orbit that overlaps with Neptune.

Ceres and Xena will also be considered dwarf planets. Charon is simply one of the "small solar system bodies."

Here are images from the Hubble Space Telescope in February that confirmed the existence of two new moons orbiting Pluto. Pluto and Charon are gravitationally locked so the same sides always face each other. They orbit each other every 6.3 Earth days.

Pluto, we love you. Be a planet again soon. Be strong.

Now let's see if this update makes it to Egyptian curiculums. Probably it'll go with 2003 UB 313 "Xena", kids will love it,being planet 10 thena couple years later they'll notice they were wrong so it'll be back to 9 for a while and finally fix it to eight.

It feels quite strange to think that we've just lost a planet, now I know how Princess Leia felt in the first Star Wars movie.... But we gain 4 'dwarf' planets, so we've still got 12 recognised bodies.... Would have been cool to have 12 planets though...

Cheers
