What do you think?

 What do you think of the definition that was formed
by the IAU?
 Do you think criteria #3 (cleared its orbit of other
objects) was written just so that Pluto wouldn’t
qualify as a “planet” anymore?
 Do you think that you could come up with a better
definition?
 Let’s try to, you will be able to get a feel for the
process scientists go through when trying to sort and
categorize their findings
Planet Categorization

 Form team of 2-3
 As a team, look through the list of criteria to consider
on page one of your handout

think would be best for creating your own definition
of what a planet is.
 Now, try writing a definition of planet of your own.
 You can include any of the parameters you wish, but
your definition can’t be the same as the IAU’s
