OR, The radius vector drawn from the sun to the planet sweeps out equal areas in equal intervals of time. Before Kepler established his laws of planetary motion in the early 17th century, mankind’s knowledge of the solar system and beyond was in its infancy and remained largely a mystery. Kepler laws of planetary motion are three laws describing the motion of the planets around the Sun. The Sun always sits in its focus. Republic Act 8293, section 176 states that: No copyright shall subsist in any work of the Government of the Philippines. Kepler’s second law: Each planet moves so that an imaginary line drawn from the Sun to … T 2 = (4 π 2 r 3 /GM) 1/2. Newton’s Law of Gravitation is states that in this universe attracts every other body with a force which is directly proportional to the product of their masses and is inversely proportional to the product of the squares of the distance between them. Kepler's Third Law: the squares of the orbital periods of the planets are directly proportional to the cubes of the semi-major axes of their orbits. Secondly, it states that a radius vector joining the sun sweeps out equal areas in equal lengths of time. 12. Encyclopædia Britannica, Inc./Patrick O'Neill Riley.
