Did You Know

The high eccentricity of Mercury's orbit would produce strange effects for anyone on the surface. For example, at some longitudes the observer would see the Sun rise and then gradually increase in size as it slowly moved overhead. Once overhead, the Sun would appear to reverse course, then stop again before resuming its path toward the horizon and decreasing in size. At night, stars would appear to move three times faster across the sky. Observers at other places on Mercury's surface would see different but equally strange motions.
