Did Johannes Kepler discover horoscopes?
No. Astrology was thousands of years old by Kepler's time. However, Kepler lived at a time when astronomy (the science) was not strongly distinguished from astrology (the pseudo-religious hooey), and one of his handicaps was that he never was fully able to get around the notion that there was some fundamental unifying "plan" behind the arrangement of the planets (he developed a model involving the Platonic solids in an attempt to explain what that plan was). Despite this, he did manage to do some solid work, probably most notably Kepler's Third Law.
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.
How did Kepler disagree with the theorys of Copernicus?
Johannes Kepler found out that planets move in ellipses and move at variable speeds as they travel round the sun. The former theory of Copernicus was not wrong, but Kepler's theory was found to be more accurate when accurate observational methods were developed. Later Kepler's theory was backed up by theory when Newton's law of gravitation came along. However in the 20th century Einstein's theory of relativity produced some small corrections to the Kepler/Newton theory.
How Kepler's assumptions about orbits different to Copernicus?
Nicholas Copernicus 1473-1543 was a Polish priest and astronomer who created an alternative model of the planets which put the Sun at the centre, instead of the Earth as generally accepted at that time.He knew it would get him into trouble with the church, and his book 'De Revolutionibus' was not published until the year he died. The theory with the Sun at the centre was similar to the old Ptolemaic system with its collection of circles and epicycles allowing for the changes in distance and the changes in planets' speeds, and their departure from the ecliptic.In the late 1500s Tycho Brahe made new more accurate observations of the planets from Denmark, and these were used by Johannes Kepler to produce a new model published in 1609.Kepler's model is the one we use today, and it has the Sun at the centre, like the Copernican model, but all the other details of Copernicus's theory were rejected in favour of elliptical orbits.
How was the discovery of the ellipse orbit made?
It was the result of hard work by Johannes Kepler, working at the start of the 17th century on new observations by Tycho Brahe. Kepler had a set of measurements of the planets' positions, and over a period of months and years he tried to explain the movements of the planets, because they did not exactly fit the old theories of Ptolemy and Copernicus. So he said to himself, let's try an ellipse, and it worked. At that stage he did not have a reason for the elliptical orbit, other than that it fitted the observations. Much later, Newton explained how a planet moving in the Sun's gravity must follow an elliptical orbit.
