what is the conclusion about the orbit of a planet
Answers
Answer: conclusion :
In physics, an orbit is the gravitationally curved trajectory of an object, such as the trajectory of a planet around a star or a natural satellite around a planet. Normally, orbit refers to a regularly repeating trajectory, although it may also refer to a non-repeating trajectory. To a close approximation, planets and satellites follow elliptic orbits, with the center of mass being orbited at a focal point of the ellipse, as described by Kepler's laws of planetary motion.For most situations, orbital motion is adequately approximated by Newtonian mechanics, which explains gravity as a force obeying an inverse-square law.[3] However, Albert Einstein's general theory of relativity, which accounts for gravity as due to curvature of spacetime, with orbits following geodesics, provides a more accurate calculation and understanding of the exact mechanics of orbit motion.

Explanation:
The mentioned situation is the basis of the Kepler's three laws of planetary motion which can be described as follows:
(1) Kepler's first law states that the path of the planets about the sun used to be elliptical in shape, with the center of the sun being located at one focus.
(2) Kepler's second law states that if an imaginary line drawn from the center of the sun to the center of the planet then the imaginary line will sweep out equal areas in equal intervals of time.
(3) Kepler's third law states that the ratio of the squares of the periods of any two planets used to be equal to the ratio of the cubes of their average distances from the sun.
