Pluto just lost its status as a planet. So now, we're left with:
7. Uranus, and
Astronomers held a meeting somewhere in the Czech capital. They were debating on whether to add 3 more planets to the current solar system or to scratch Pluto out since so many other "Plutos" have been discovered since the 1990s. Now we now which one won the vote...
Wow. Can you believe it?
This all happened when they came up with a new definition of a planet:
To qualify as a planet, a celestial body must be in orbit around a star while not itself being a star. It also must be large enough in mass "for its self-gravity to overcome rigid body forces so that it assumes a... nearly round shape, and has cleared the neighbourhood around its orbit."
Pluto was automatically disqualified because its oblong orbit overlaps with Neptune's.
It will now join a new category of "dwarf planets".
