More About Rotation IV
3. Here We Are, 'Round the Sun...
This brings together all three of the previous mini-lessons about
rotation of the Earth. You see the Earth rotating on its axis, and
also going around the sun. The solstices and equinoxes will briefly
flash on the screen for each time of year.
NOTE: This is not to scale; in reality, the sun is a lot bigger to
scale, and Earth is a lot further away.
