nobody believe in the planets at first
yes, in 2015 scientists think new planets will be created
No. scientists have found dozens of planets about the same size as Eris and Pluto. I think they should just be Dwarf planets.
When the sun was being born, matter that was circling around it formed into planets. There was hundreds of planets, but most of them were destroyed when they crashed into each other. Eventually, only the main 8 planets were left. Then water came on earth from comets.(scientists think so anyway) and life was formed
The instrument scientists use to observe the planets is a high powered telescope.

ummm there were nine planets but scientists decided that Pluto was a dwarf planet so i don't think it counts anymore
