Kepler's laws of planetary motion are three scientific laws describing the motion of planets around the Sun. Kepler's laws are now traditionally enumerated in this way.

Kepler’s first law- Law of orbits
Every planet revolves in an elliptical orbit around the sun. The orbit of every planet is an ellipse with the Sun at one of the two focii.

Kepler’s second law- Law of equal areas
A line joining a planet and the Sun sweeps out equal areas during equal intervals of time.

Kepler’s third law- Law of periodsThe square of the orbital period of a planet is directly proportional to the cube of the semi-major axis of its orbit.

Black holes:-
​Ablack holeis a region ofspacetimeexhibiting such stronggravitationaleffects that nothing—includingparticlesand electromagnetic radiationsuch as light—can escape from inside it.

hello,
kepler invited three laws.1.law of orbits 2.law of equal areas 3.law of periods
backhole means the highly gravitational force having in the universe.this means planets are attracting towards this which having highly gravitational force.
