Detailed explanation-1: -For example, moons orbit around planets; planets around stars; stars around the center of the galaxy, etc.
Detailed explanation-2: -Rotation and Revolution For example, Earth rotates on its own axis, producing the 24-hour day. Earth revolves about the Sun, producing the 365-day year. A satellite revolves around a planet.
Detailed explanation-3: -Kepler’s Laws of Planetary Motion They describe how (1) planets move in elliptical orbits with the Sun as a focus, (2) a planet covers the same area of space in the same amount of time no matter where it is in its orbit, and (3) a planet’s orbital period is proportional to the size of its orbit (its semi-major axis).
Detailed explanation-4: -that the movement of the world on its axis. The movement of the world round the sun during a fixed path or orbit is named Revolution. There are 2 sorts of motion: Rotation and revolution. Rotation: A rotation may be a circular movement of an object around a center of rotation.
Detailed explanation-5: -Rotation and revolution are the two motions of the Earth. Rotation is the movement of the Earth about its axis. Revolution is the movement of the Earth around the Sun in a specific orbit.
