What is Kepler first law?
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.
Which scientist discovered that planets move in ellipse?
It was months and years of difficult geometrical calculations from measurements made by Tycho Brahe, by his employee Johannes Kepler. When Tycho was alive he would not let Kepler see the results of his work, but he let slip a few figures, tantalisingly, now and again. But after Tycho's death Kepler was clever and devious enough to get his hands on the results, which was fortunate because he had the ability to make use of them. Kepler chose the orbit of Mars as a special subject, which was lucky because it has a relatively high eccentricity that shows up the difference between an ellipse and a circular orbit. After some false starts he realised that the figures fitted an elliptical orbit. Subsequently further observations demonstrated that elliptical orbits gave correct predictions of the positions of Mars and the other planets. Kepler used the heliocentric principle, with the Sun at the centre. Although Kepler and Galileo were contemporary, Galileo never believed that the planets' orbits could be elliptical, and he stuck to the old systems of circles and epicycles of Ptolemy and Copernicus.
Do we use Kepler's Model in modern astronomy?
Yes, Kepler's laws of planetary motion are still used in modern astronomy to describe the motion of planets and other celestial bodies in our solar system. Kepler's model provides a foundation for understanding orbits and predicting the positions of planets accurately.
How did Kepler figure out that planets orbit is elliptical?
Kepler, the person who first wrote about elliptical orbits, had a Trinitarian view of the solar system in which it made perfect sense theologically to have the Sun at the centre of the universe. Copernicus also believed in a Sun-centred system.
Which astronomer discovered the orbit of planets?
Newton Copernicus is credited for hypothesizing the heliocentric solar system. Kepler had the equations to determine the orbits, but didn't know "why" these figures worked. Galileo's observations confirmed these things, but it was Newton's laws of motion that explained the "why."
How did Kepler us tycho brahe's data?
Kepler used Tycho Brahe's data by developing his Laws of planetary motion and by analyzing his observations about planet's orbit.! :D
What kind of orbit did Kepler use?
Elli[tical orbits.
How did Kepler formulate his third law?
Kepler's 3rd law says that the orbital period is proportional to the 3/2 power of the average distance from the Sun. However Kepler did not know the distances to the planets when his laws were discovered. He was able to calculate the the relative distances by using geometry. In Kepler's model the inner planets stay close to the Sun in the sky and have a maximum 'elongation' from it. Kepler was able to use these measurements to deduce by geometry what the sizes of the orbits of Mercury and Venus were, relative to the size of the Earth's orbit. The outer planets all show retrograde motion around the time of opposition, as the Earth overtakes the planet. By knowing the amount of retrograde motion measured by Tycho, Kepler was able to deduce by geometry the sizes of the orbits of Mars, Jupiter and Saturn, relative to the size of the Earth's orbit. The true scale of the planets' orbits was discovered in the 18th century through observations of transits of Venus.
What is the main difference between Kepler's system and Copernicus system?
The main difference between Kepler's system and Copernicus' system lies in their approach to planetary motion. Copernicus proposed a heliocentric model, where the Sun is at the center of the solar system, while Kepler's model focused on the elliptical orbits of planets around the Sun. Copernicus' system laid the groundwork for a sun-centered model, while Kepler's laws of planetary motion provided a more accurate description of the paths planets take as they orbit the Sun.

Which scientist would have been most likely to use mathematics in understanding elliptical orbits of planets?
Kepler, probably.
What forces does the sun use to keep the planets in orbit?
solar power
What aspects of the planets orbits are nearly the same for most planets?
1. Planets in the orbits all conform to Kepler's three laws of planetary motion, 2. The orbits are all nearly in the same plane,3. The orbits are all elliptical, but not very ellptical and near-circular in shape, with the Sun slightly off-centre.Added:p2 = a3P. The planetary orbital period in earth years.a. Distance from sun in astronomical units, based on 1 AU for earth. ( for example, Mars would be about 1.5 AU and you would use this value in the equation, not the actual distance )
Why do we use math?
it goes hand in hand with science and can accurately prove theories. for instance we discovered that planets orbit in elliptical shapes (like an oval) by math by Kepler. We use it to work out nearly everything we do, from calculating the time, making change when we buy and sell we use it to calculate weights , volume it is an important aid in nearly everything we do.
What would be the average distance of a planet from the Sun with a orbital period of 730 days?
Use Kepler's Third Law, and compare with Earth's orbit.
