Question

what is keplar's law of planetary motion???​

Answer 1

Answer:

Explanation:

Kepler’s three laws of planetary motion can be stated as follows:

(1) All planets move about the Sun in elliptical orbits, having the Sun as one of the foci.

(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.

DID YOU KNOW?

Kepler was the assistant of Tycho Brahe, a prevalent astronomer who worked before the invention of the telescope.

Kepler reached his conclusions while using Brahe's careful astronomical observations to define the orbit of Mars.

Kepler confirmed that Galileo's heliocentric view of the universe (as opposed to Brahe's more popular, mostly geocentric view of the universe) was correct.

Answer 2

There are actually three, Kepler's laws that is, of planetary motion: 1) every planet's orbit is an ellipse with the Sun at a focus; 2) a line joining the Sun and a planet sweeps out equal areas in equal times; and 3) the square of a planet's orbital period is proportional to the cube of the semi-major axis of its
