Posted by Annette on 5/22/08 How old is your textbook? A few years back Pluto was declared a dwarf planet because it didn't meet the criteria of what makes a planet a planet. If I remember correctly it mostly had to do with the orbit of Pluto. Pluto has a more eliptical orbit pattern compared to the other planets. The question of Pluto being a planet came about because of another planet that was discovered that was very similar to Pluto. So scientists brainstormed a list of characteristics that planets should have in order to be considered a planet. It just so happened that Pluto didn't meet all of the characteristics. Hope this helps. On 5/22/08, carma lupe wrote: > On 4/21/08, 4th grade wrote: >> Is pluto a planet? Our science book says that it is.
