Kepler law |
| Answer» Kepler’s three laws of planetary motion are: • The law of orbits • The law of areas and • The law of periodsKepler’s first lawKepler’s first law, the law of orbits, states that the orbit of a planet is an ellipse with the sun at one of the foci.\xa0An ellipse is a closed, curved shape that is defined by two points called foci representing an elongated circle.The closest point on a planet’s orbit from the sun is called perihelion and the farthest point from the sun is called the aphelion.\xa0Kepler’s second lawKepler’s second law of planetary motion, also known as the law of areas, states that the line joining the planet to the sun sweeps out equal areas in equal intervals of time as the planet \xa0 travels in its orbit.Kepler’s third law\xa0Kepler’s third law, the law of periods, defines the relationship between the orbital period of a planet and the average radius of its orbit.\xa0The orbital period of a planet, denoted by T, is the time taken by the planet to make a complete revolution around the sun along its orbit. | |
