If future experimental data will show that Newton's Version of Kepler's Third Law does not accurately describe motion of planets in a number of planetary systems, then:

These experimental data should be ignored.

Newton's Version of Kepler's Third Law needs to be immediately revised, without checking experimental data.

Newton never revised Kepler's Third Law of planetary motion.

These experimental data needs to be carefully checked and, if they are accurate -Newton's Version of Kepler's Third Law needs to be revised for these planetary systems.

Newton's version of Kepler's Third Law should be immediately abandoned
