Whats The Tenth Planet Called

[Marty_Pellow]

What is the tenth planet in our solar system called? and where can i see pictures of it?

Mecury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto what is the tenth planet they found a few years back called?

well they did find 1 they called it Segna but i don't think it's a proper planet because they had a massive debet about it i think the made it a planetiod (a cross between a planet and a asteriod)

I think it's up to 11 now; there is Sedna, and i think one called Quohor. Again, there is debate wether these are actual planets,or that they are part of the Kuipier belt.xx

They are not considered planets because they are not big enough.  The dividing line between planets and non-planets is arbitrary; there is a lot of junk and lumps out there waiting to be discovered - like Quaoar and Sedna.

There is/was a debate over whether Pluto was big enough to be labelled as a planet. Until now I thought that our solar system was at risk of getting smaller, not bigger

[bernardo]

If Pluto had been discovered now, it probably would not be called a planet.  Similarly, if Quaoar had been discovered in 1930, it probably would have been.  It is only in recent times that astronomers have realised that the whole place is cluttered up with loads of stuff, so to count Quaoar and Sedna as planets would be a dangerous precedent which could result in the number of "planets" going up astronomically (pun).
