1. As per Kepler's first law. every planet revolves around the sun in an elliptical orbit where the sun is situated at one of its focii.
2. second law:- the square of the time period is directly proportional to the cube of semi major axis. I,e T²&a³. & directly proportional

Answer 2

Hey here is your answer:-

Johannes Kepler has given the three laws of planetary as follow :

First Law:

The planets move in elliptical orbits around the sun, with the sun at one of the two foci of the elliptical orbit.

Second Law

Each planet revolves around the sun in such a way that the line joining the planet to the sun sweeps over equal areas in equal intervals of time. A planet moves faster when it is closer to the sun, and moves slowly when it is farther from the sun.

Third Law

The cube of the mean distance of a planet from the sun is directly proportional to the square of time it takes to move around the sun.
