A) Astrology played an important part in the development of astronomy in ancient times, but it is not a science by modern standards. The formula to calculate the orbital period of a satellite around the central body is T = [3 / (G * )] Where, T is the orbital period. The Law of Orbits: All planets move in elliptical orbits, with the sun at one focus. C) It is the name given to sphere-shaped models that show all the constellations as they appear in our sky on the celestial sphere. E) All of the above are correct. Kepler's Third Law. Which one follows directly from Kepler's third law (p2 = a3)? C) 2 Earth years. For an ellipse, recall that the semi-major axis is one-half the sum of the perihelion and the aphelion. To do this, astronomers use the binary mass function, which is derived from Keplers third law and the fact that bodies orbit a mutual center of gravity. This sentence reflects the relationship between the distance from the Sun of each planet in the Solar system and its corresponding orbital period (also known as the sidereal period that we described in the synodic period calculator).
