Pluto and Ceres

By: Alex Kharkiv and Jennifer Major


Pluto and Ceres are two dwarf planets because they're too small to be planets. Pluto was once a planet, but a few years ago it was considered a dwarf planet. Ceres is the biggest object in the asteroid belt. Even though Pluto is bigger than Ceres, they are still very similar.


  • Once considered a planet, but now it is a dwarf planet.
  • Pluto experiences strong winds when its atmosphere is present.
  • One of the coldest places in the solar system.
  • Hubble shows that Pluto had grown redder over time. (seasonal changes)
  • It takes Pluto 248 years to orbit the sun.

  • Pluto has 3 moons.
  • It sometimes crosses in front of Neptune's orbit, and becomes the 8th object from the sun.

Pluto's Moons


  • Smallest and closest dwarf planet
  • Smallest known dwarf planet, but largest object in the asteroid belt.
  • Scientist think it may have and ocean and possibly an atmosphere.
  • A probe will be sent in 2015.
  • Has iron-rich clay.
  • -30 degrees Celsius
  • Orbits between Mars and Jupiter's asteroid belt.
