-- If you want to send a space ship from the earth to, let's say, Mars, you need to know how Mars is going to move, so that you know what kind of transfer orbit to put the space ship into, and to be sure that Mars will be there when the ship gets there. Kepler's laws tell you how Mars moves. -- If you want to send a space ship from the earth to, let's say, Mars, you need to know how it will move once it leaves the earth and its rockets shut down. Kepler's laws tell you how the space ship is going to move. -- If an astronaut wants to put on his space suit, step out of the Shuttle, and take a little space-walk around, he'll want to know how HE will move once he's outside, so that he can be sure not to float too far away from the Shuttle. Kepler's laws tell how HE will move in his orbit around the earth.
Kepler's second law the law of equal areas.
Celestial objects in orbit.
Keplers Laws
It is the third 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.
Kepler's second law the law of equal areas.
Celestial objects in orbit.
Keplers Laws
It is the third law
Known for his eponymous laws of planetary motion.
Mindboggling? They are "Laws of Planetary Motion". So I guess the answer is "motion".
Isaac Newton
he supported his ways and thiught of better ways to replace keplers half right ways
Distance from the body and the mass of the body. See Keplers laws of planetary motion for more info.
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.
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.
April 27, 4977 B.C. That was when he once calculated that the universe began. Or, you may mean when he published his Laws of Planetary Motion. He published his first 2 laws in 1609 and his 3rd law around 1619.
