It is the third law
Mindboggling? They are "Laws of Planetary Motion". So I guess the answer is "motion".
This is known as Keplers 2nd Law of Planetary Motion. It states that line drawn between a planet and the sun sweeps out equal areas during equal time intervals.
Kepler's second law the law of equal areas.
Newton derived Keplars findings from Newton's Theory of Gravity. Thus, newton 'explained' the basis for Keplars findings and extended them.
Kepler's first law says Neptune has an elliptical orbit with the Sun at one focus. The same goes for the other planets.
... when it is closest to the Sun. (Kepler's Second Law)... when it is closest to the Sun. (Kepler's Second Law)... when it is closest to the Sun. (Kepler's Second Law)... when it is closest to the Sun. (Kepler's Second Law)
These three variables are related by Newton's Second law: Force = mass x acceleration.
Yes. Three sisters (only related through their mother) and three sisters-in-law.
It is Kepler's first law which says the planet moves in an ellipse with the Sun occupying one focus and the other focus is vacant.
because kepler was smart
Celestial objects in orbit.
