this is a 3 tracks EP inspired by the Kepler's three laws.
"Our knowledge of the state of motion of the planets was obtained by a slow surveying process. (...) 1. The orbit of each planet is an ellipse with the Sun at the focus. 2. The line joining planet and Sun sweeps over equal areas in equal intervals of time. 3. The ratio of the cube of the mean distance from the Sun to the square of the period is the same for all planets. Kepler's three laws contain a clear and complete statement of the actual state of motion of the planets." (from BASIC ASTRONOMY, Peter Van De Kamp, Random House, USA, 1952)
