Hubble Observations of Ceres and Pluto: A Closer Look at the "Ugly
Ducklings" of the Solar System
by Max Mutchler, Space Telescope Science Institute
Pluto has made the news quite often since August, when the
International Astronomical Union voted on the definition of a planet
and in the process "demoted" Pluto to a dwarf planet. Why isn't Pluto
a planet anymore? Are there are other objects like Pluto in our Solar
System? Find out more in this issue of the Universe in the Classroom.
Topics include:
* The history of the number of planets in our solar system
* Ceres, the dwarf planet in the asteroid belt
* Pluto's fate
* Missions to Pluto and Ceres
* Two classroom activities about the scale and structure of the
Solar System
