SOLAR SYSTEM

Detailed explanation-1: -Kepler’s third law states that square of period of revolution (T) of a planet around the sun, is proportional to third power of average distance r between sun and planet. i.e T2=Kr3 here K is constant.

Detailed explanation-2: -Kepler’s Second Law characterizes the the velocity of a planet along its elliptical path. Kepler’s Second Law says says that a line running from the sun to the planet sweeps out equal areas of the ellipse in equal times. This means that the planet speeds up as it approaches the sun and slows down as it departs from it.

Detailed explanation-3: -Kepler’s Law of equal areas for equal times. As a planet moves in an orbit about the Sun, the areas swept out by the planet are equal for equal time intervals. A: For circular orbits the equal areas are identical in shape and size (red areas).

Detailed explanation-4: -Kepler’s third law : The square of its period of revolution around the Sun is directly proportional to the cube of the mean distance of a planet from the Sun.
