The Earth as Seen from the Moon
The Earth as Seen from the Moon
In 1608 Johannes Kepler wrote Somnium (The Dream), presenting a description of the Earth as seen from the Moon. This Demonstration illustrates some features of his view, from a point at about 45° latitude on the central meridian of the near side of the Moon, in the circular orbit approximation. The "view from space" option also allows an overview of the Sun-Earth-Moon system from the selenocentric (Moon-centered) point of view.
