why do we need the law? what is their goal? how are they utilised right now?
I am just trying to comprehend the law and why they are essential to this field.
Answer by oklatonola
There are three laws of planetary motion, not one. All of orbital/celestial mechanics, like sending probes to each single planet, such as Pluto, is based on Kepler’s three laws of planetary motion, which preceded Newton’s “Principia”. Newton stated that Kepler’s laws conformed and confirmed his 3 laws of motion.

Kepler’s laws are important because they are the rules of our solar program. Guidelines that are always correct. They are important since you can use his laws to figure out other factors within our universe.

Kepler built his laws utilizing the observations of at least two other astronomers (in addition to his own) to have a dataset spanning at least 3 lifetimes. A dataset of this size is essential to find the coherence in the pattern provided by daily observation, and he was really the 1st to have it.
Prior to Kepler, there were no relationships providing an accurate predictive measure of the location of the heavenly bodies. A single appear at a time-lapse video of a single section of evening sky spanning a year will show you why discovering that coherence is so tough. [It also gives a excellent illustration of why the ancient Greeks equated the motion of the sun, the moon and the planets (large vibrant stars) with the gods racing their chariots across the sky (seemingly arbitrary beginning points from evening-to-night, but following a simple trajectory if you do not look also closely, but seeking back-tracking trajectory patterns if you pay interest for lengthy sufficient.)
The laws are nice since they condense the outcomes of difficult synchronized elliptical motions into sets of easy algebraic relations (appropriate for use on college exams.)
Right now, they’re primarily used in “back of the envelope” calculations, and to verify pc models for celestial motion and for extraterrestrial navigation (sending probes to other planets/comets/asteroids/and so forth.) [If your pc model does not satisfy the Kepler relations, you much better check your implementation once again!]
