Teacher's Note<br />
Make sure to point out to learners about the length of time it takes<br />
each learner to orbit the Sun. When Neptune has completed one<br />
revolution, Mercury will have completed many more as it is closer<br />
to the Sun. Point out the big gap between Mars <strong>and</strong> Jupiter – the<br />
space between the inner <strong>and</strong> outer planets. Mention to learners<br />
that there is actually a ring of asteroids (giant rocks) that also orbit<br />
the Sun in this space.<br />

orbit.<br />
