Detailed explanation-1: -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-2: -Kepler’s Second Law Describes the Way an Object’s Speed Varies along Its Orbit. A planet’s orbital speed changes, depending on how far it is from the Sun. The closer a planet is to the Sun, the stronger the Sun’s gravitational pull on it, and the faster the planet moves.
Detailed explanation-3: -Originally formulated to describe the movement of planets around the Sun, Kepler’s laws apply to any system where one body orbits another, including moons around planets, artificial satellites around Earth, and exoplanets and their host stars.
Detailed explanation-4: -The third law expresses that the farther a planet is from the Sun, the slower its orbital speed, and vice versa.
