How would you define a planet's orbital period? For the terrestrial planets, what is used as a benchmark in comparative planetology and why? Earth, because we know the most about it.
All planetary orbits are nearly circular and lie nearly in the same plane. All planets orbit the Sun in the same direction: Counterclockwise as viewed from high above Earth's North Pole. Most planets rotate in the same direction in which they orbit with fairly small axis tilts.

Orbits of the Planets. Today, Newton’s work enables us to calculate and predict the orbits of the planets with marvelous precision. We know eight planets, beginning with Mercury closest to the Sun and extending outward to Neptune. The average orbital data for the planets are summarized in Table 3.2.
The inner planets, or terrestrial planets, are the four planets closest to the Sun: Mercury, Venus, Earth, and Mars. Figure below shows the relative sizes of these four inner planets. This composite shows the relative sizes of the four inner planets.
10 Απρ 2022 · Key Concepts and Summary. The closest point in a satellite orbit around Earth is its perigee, and the farthest point is its apogee (corresponding to perihelion and aphelion for an orbit around the Sun). The planets follow orbits around the Sun that are nearly circular and in the same plane.
