Johanes Kepler was a German astronomer. He revised the heliocentric model by demonstrating that the orbits are ellipses.
glad if that helped you out :) xx

Kepler's first law worked where Copernicus' original heliocentric model failed because Kepler described the orbits as?
Copernicus's theory did not fail but it was not as accurate as the Kepler model because it did not include elliptical orbits for the planets, as Kepler's model did. However the data for calculating the elliptical orbits did not become available until well after Copernicus's death so he had no chance of knowing about this change. Copernicus's model which used circles and epicycles was accurate to the standard of the observations that were available to him.
Who introduced the idea of a heliocentric model of telescope that uses mirrors?
I believe you are confusing two things here; there is no such thing as a "heliocentric model of telescope". There is a heliocentric model of our Solar System, and there are telescopes. The two are unrelated.
Why is Uranus and Neptune not included in the heliocentric and geocentric model of the solar system?
The planets Uranus and Neptune were discovered only in modern times after the heliocentric model had been generally accepted.
Does Judaism accept the heliocentric model?
Are there any civilized peoples on earth who do not?
What planetary model allows scientists to predict the exact positions of planets in night sky over many years?
Either the heliocentric or the geocentric model would allow predictions of thefuture motions of the planets. It was not the inability to predict that sackedthe geocentric model. It was the simplicity of the heliocentric model. Kepler'shypothetical ellipses helped a lot, and Newton's gravitation sealed the deal,when he showed that heliocentric, elliptical planetary orbits, just as Keplerdescribed them, had to spring forth from gravitation.
Who replaced circles with In a heliocentric model of the universe?
Johannes Kepler
Who replaced circles with ellipse in a heliocentric model of the universe?
Johannes Kepler
Who replace the circles with ellipses in a heliocentric model of the solar system?
Johannes Kepler
What conclusion did Kepler eventually come to that revolutionized the heliocentric model of the solar system?
kepler determined the planetary orbits were elliptical
Which scientists gathered data that confirmed the heliocentric model of the solar system?
i think it's Kepler
Why do scientists not believe in ptolemaic model?
because the work of Tycho and Kepler showed the heliocentric model was more accurate.
What is helio centric model?
A heliocentric model is a model of the planets' movements that places the Sun at the centre of the Solar System. Copernicus's model published in 1543 was the first heliocentric model. It resembled the Ptolemaic model in respect of the circles and epicycles that were used to explain the planets' movements. Kepler's model published in 1609 was also heliocentric, but it used planar elliptical orbits for the planets, which follow Kepler's 3 laws of planetary motion. It is now the accepted model.
What are the strengths of the heliocentric model?
Its main strength is that it is the model which is universally accepted by everyone. Copernicus put forward a heliocentric model that used circular orbits. That meant he couldn't completely eliminate all the complications of the old geocentric model, such as "epicycles". Later Kepler showed that the planets move in elliptical orbits. The basic idea of the heliocentric model is that the Sun is at the centre. One of the main strengths is the simplicity of the heliocentric model. Kepler's version (still used today) of the model with its elliptical orbits is particularly elegant and simple, with no epicycles.
What are Six early ideas about planetary motion?
Eccentricity, geocentric model, heliocentric model, Kepler's second and third laws, elliptical orbits, and Newtons gravitation
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 replaced the circle in with ellipse's in the heliocentric model of the universe?
Copernicus's Sun-centred (heliocentric) model of the planets' orbits used circles and epicycles, as the Ptolemaic model had done although the older model had the Earth at the centre. Kepler took the heliocentric idea and used it as the basis for extended calculations on the orbit Mars using new observations and measurements of unprecedented accuracy by his employer, Tycho Brahe. Mars's orbit had just enough eccentricity (9%) to allow a difference to show up between the earlier model and Kepler's new discovery of eliptical orbits. Kepler also found that the other planets had elliptical obits, but the eccentricity was lower. He developed his three laws of planetary motion now known as Kepler's laws.
Who were the two people that believed in the heliocentric model of the solar system?
The heliocentric idea, with the Sun at the centre, was part of a prediction model using circles and epicycles devised by Copernicus, called the heliocentric model. The heliocentric idea was adopted by Kepler in his work that led to the discovery of Kepler's laws of planetary motion. It was also used by Galileo in a famous dispute with the Catholic church which was not about to change its ideas without adequate evidence. The evidence came after Galileo's time when Newton made the necessary theoretical discoveries to understand the way the Sun's gravity produces planets' orbits. Since then everyone believes that the Sun is at the centre.
