The Moon orbits the Earth at a speed of 2,288 mph. It advances 13° each day, completing a full circle in 28 days. During the full moon, I set up an equatorial mount to track the moon across the night sky. I left the equipment untouched and locked in position for two weeks, until the moon was in its second quarter and the sky was darker. I repeated the experiment with the same tracking settings to capture an image of the stars. The results reveal the speed of the Moon’s orbit: the stars appear as streaks because the mount still follows the Moon’s path, not theirs.
