Question

what are kepler's law?

Answer 1

Keplar's Laws of Planetary Motion are as follows:
1) All planets move around the sun in elliptical orbits, having the sun as a focii.
2) A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time.
3) The squares of the sidereal periods of revolution of the planets are directly proportional to the cubes of their mean distances from the Sun.

Kepler's Law➫ A law state that the orbit of each planet is an ellipse with the sun at one focus of the ellipse.

▸ This law is also known as - Kepler's Law 0f Planetary Motion.

➧The Kepler's Laws are:-▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃⤵

❶❫ Laws 0f 0rbit:-▬▬▬▬▬▬▬▬▬▬☟

Every planets revolves around the sun in an Elliptical 0rbit with the Sun situated at one of the foci of the ellipse.

❷❫ Laws 0f Area:-▬▬▬▬▬▬▬▬▬▬☟

Each planets moves in a such a way that an imaginary line drawn from the sun to the planets sweeps out equal area in equal intervals of time.

❸❫ Laws 0f Time Period:-▬▬▬▬▬▬▬▬▬▬▬☟

The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its 0rbit.
