The Planets
Hi I'm Caleb Newman and my family has been arguing about how Pluto isn't a planet or if there are more out there. Well I would like you to give me your opinion on the subject so just give me a comment and I'll take a look. I believe that there are more planets out there for future technology to discover. But I still am 50-50 on Pluto because it may just be the distance between us that makes it look small. When my friends say something like "How do you know" I simply tell them "Nobody on the present Earth man or machine has ever been to Pluto" But I want you to tell me what you think about it. If you would like me to reply to you just tell me your e-mail and I will write back. I will not tell anyone your e-mail address for I shall keep it to myself.
Sincerely,
Caleb N

It is totally possible that there are more Pluto-sized dwarf planets in our solar system - in fact scientists have identified 4 so far and there may be more.
Ceres (discovered 45 years before Neptune) is in the asteroid belt between Mars and Jupiter and was considered a planet for half a century before reclassification as an asteroid. It was reclassified again, this time as a dwarf planet in 2006.
Haumea (discovered in 2004), Eris (discovered in 2005) and Makemake (discovered in 2005) are all dwarf planets in the Kuiper Belt beyond Neptune.
