yes
Planet X does exist but there are about 3 Dwarf planets that have simularities to Plznet X. Planet X has not yet been discovered.
MABEY
honestly i say no.
yes they are. :D
Planet x is the name used to name undiscovered planets that might exist. The belief that an actual "Planet X" is out there and on a collision course with Earth is a different story. If you ask these people they'll tell you it's really, really, close and we're all in deep, deep...
NO! And the proof is its already 2013 no hit and earth isnt in the middle of the solar system and many planets are in it so I say planet x isnt going to collide with earth and if it is a meteorite then theres a really big chance planet x hits the huge sun and melts there
Planet X was a hypothetical planet which was searched for after the discovery of planet Neptune. `Planet-X` does not exist.
Not really.
No, Planet X does not exist.
Don't think so. Some scientists think that but others thought it was just a really big meteorite.
No
Planet x is the planet behind Pluto which is commonly reffered to as Selena but is not yet a planet(or clarified planet).
