No. It holds for other planets, and for any other situation where one objects orbits another - for example, moons orbiting planets, stars orbiting a black hole, etc.
It is the third law
Kepler's second law the law of equal areas.
Celestial objects in orbit.
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.
Keplers Laws
It is the third law
Known for his eponymous laws of planetary motion.
Kepler's second law the law of equal areas.
Johannes Kepler(1571-1630) was a German astronomy and natrual philosophere who was known for his ability in formulating and verifying the three laws of planetary motion, which are now known as Keplers's Laws.
Celestial objects in orbit.
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.
Keplers Laws
Mindboggling? They are "Laws of Planetary Motion". So I guess the answer is "motion".
Isaac Newton

Johannes Kepler was the scientist who included three laws of planetary motion as part of his heliocentric theory of the universe. These laws, known as Kepler's Laws of Planetary Motion, describe the orbits of planets around the Sun.
Kepler's Laws of Planetary Motion:1] Each planet moves in an elliptical orbit with the sun at one focus2] The line form the sun to any planet sweeps out equal areas of space in equal time intervals3] The squares of the times of revolution (days, months or years) of the planets are proportional to the cubes of their average distances from the sun.
