Transcript Planet Rotation and Revolution

The purpose of this
presentation is to help
you understand the
terms of rotation and
revolution as it relates
to the planets in our
solar system. How
does the animation to
the right show the
meaning of these
words?
Models are not to scale and orbital paths are not accurate
Before Pushing Start…
Try to make a hypothesis of what will
happen
– Will the planet start spinning on it’s axis or
orbiting the sun?
– Will it rotate or revolve faster or slower
compared to the Earth?
– How will it’s rotation compare to it’s
revolution?

Discussion
Which planets have days longer than
their years?
Compared to Earth would a planet with a
12 hour day have a shorter or longer
rotation?
Which planet would you have to wait the
longest to have your birthday every
year?
Which planet would rotate the most in
one year?
