English: "The solid body of Venus rotates more slowly at present day than any terrestrial planet in our Solar System. This cartoon depicts the orbit of Venus around the Sun, viewed from above. The orbital angles are approximately to scale, but the relative sizes of Venus and the Sun are not. After one solar day (a), an observer at a fixed location on the surface of Venus would see the Sun return to its original position in the sky. In one year (b), Venus completes a single orbit around the Sun. In one sidereal day (c), Venus revolves once relative to the celestial sphere (e.g., the background stars). Earth’s sidereal day is shorter than its solar day, which is much shorter than our year. In contrast, a Venus-year lasts less than two of its solar days—and one sidereal day on Venus is longer than a Venus-year"^[1]
