Who was the scientist first that stated that the paths of planets are ellipses instead of circles?
It was Johannes Kepler at the start of the 17th century. He studied new observations done by Tycho Brahe and after many months doing calculations from the measurements of the path of Mars he concluded that an ellipse was the best way to describe the orbit because it gives predictions that are the closest to the real thing.
Why did it take so long when they had been studying this for 1500 years? it was because the previous model, based on circles and epicycles, gave results that were accurate enough until Tycho Brahe's more accurate observations showed that something was not quite right.
Luckily for Kepler, the orbit of Mars has more eccentricity than the other major planets and this was the right orbit to study if he was going to reach a result.
What else can I help you with?
One of the discoveries that led to the modern view of the Solar System was that the BLANK of the planets were ellipses?
One of the discoveries that led to the modern view of the Solar System was that the orbits of the planets were ellipses. This was one of the key contributions from Johannes Kepler's laws of planetary motion, which replaced the earlier belief that planetary orbits were perfect circles.
Are all planetary orbits ellipses?
Yes, according to Kepler's laws of planetary motion, all planetary orbits are elliptical in shape. This means that planets do not orbit the sun in a perfect circle, but instead follow an elliptical path with the sun at one of the foci of the ellipse.
Shape of planets' orbits discovered by Kepler?
ellipses.
Which astronomer discovered that the planets orbit the sun in oval shaped paths called ellipses?
Kepler discovered that the planets orbit the sun in oval shaped paths called ellipses.
What kind of orbits do most planets have?
Most planets have elliptical orbits around the Sun. These orbits are slightly elongated circles, with the planet closer to the Sun at one end (perihelion) and farther away at the other end (aphelion).
What scientist first stated that the paths of planets are ellipses instead of circles.?
Johannes Kepler
What date did Johannes Kepler discover ellipses?
Kepler did not discover ellipses. In 1605 he discovered that the orbits of the planets were ellipses rather than perfect circles.
Who replaced circles with ellipses in a helicentric model of the universe?
Johannes Kepler replaced circles with ellipses in the heliocentric model of the universe.
What is the difference between Copernicus and Kepler description of planetary orbits?
Kepler realised the planets orbits are not circles; they are ellipses.
Do planets move in elliptical orbits?
The planets move intheir ellipticalorbits becauseof the gravitation of the Sun combined withthe inertial velocity of the planets(tangentialto their orbital paths). Mathematics shows the resulting orbits must be ellipses. (Some of the ellipses are in factalmost circles.)
How did Kepler improve Copernicus theory?
He discovered that planets move in ellipses not circles and that the sun stays in it's own place.
What are ellipses?
Ellipses are a scientific word for the shape of an oval. for example the planets orbits are ellipses.

What of the planets are ellipses?
their orbits
The greatest inaccuracy in Copernicus' model of the solar system was that the planets?
The greatest inaccuracy in Copernicus' model of the solar system was that he still believed that planets moved in perfect circles, when in fact they move in ellipses. This led to inaccuracies in predicting planetary positions.
Who worked out that the planets orbits are flattened circles?
Johannes Kepler, using measured planetary positional data provided by Tycho Brahe, showed that the orbits of the planets were ellipses ("flattened circles"), with the Sun at one focus of the eliipse.
Who used ellipses for the planets?
Twilight
