Johannes Kepler
The circular orbits that were being used at the time to model the solar system did not quite work with mathematical predictions or observations. Kepler found that elliptical orbits provided more accurate predictions of where the heavenly bodies would appear in the sky.
Johannes Kepler proposed in the early 17th century that the orbits of planets are elliptical with the Sun located at one of the foci. This was one of his three laws of planetary motion, which revolutionized our understanding of celestial mechanics.
According to Keplers first law of 1618 which has not been repealed yet, the planets each move in an elliptical orbit with the Sun occupying one focus. The shape of an ellipse is described by the eccentricity. For low eccentricity such as the planets' orbits have, the orbit is very close to being a circle but the most significant difference is that the Sun is off-centre.

Johannes Kepler was the first person to prove that all of the planets are in elliptical orbits, but he was unable to propose any mechanism that would cause this. Based largely on Kepler's work, Isaac Newton was able to invent the calculus of infinitesimals and to propose his law of universal gravitation, providing a mechanism that would cause the planets to behave in accordance with Kepler's laws. Newton's later comment "If I have seen further than other men, it is because I have stood on the shoulders of giants" was in direct reference to Kepler's essential contributions.
It was Johannes Kepler.
Johannes Kepler in the early 17th century. He developed his three laws of planetary motion, with the first law stating that planets move in elliptical orbits with the Sun at one focus.
Kepler's first law of planetary motion published in 1618 says that the planets travel in elliptical orbits with the Sun at one focus. Newton's law of gravity and other work he did explains how the Sun's gravity produces ellpitical orbits.
The circular orbits that were being used at the time to model the solar system did not quite work with mathematical predictions or observations. Kepler found that elliptical orbits provided more accurate predictions of where the heavenly bodies would appear in the sky.
Johannes Kepler was the first to state that planets move in elliptical orbits.
Johannes Kepler stated that the planets moved in elliptical orbits around the sun. This was one of his three laws of planetary motion, which he published in the early 17th century. These laws revolutionized our understanding of the solar system and replaced the previously held idea of circular orbits.
17th century astronomer Johannes Kepler discovered the elliptical shape of the planets' orbits around the Sun, which he described in his first law of planetary motion. Newton later explained this in his law of universal gravitation.
Johannes Kepler proposed in the early 17th century that the orbits of planets are elliptical with the Sun located at one of the foci. This was one of his three laws of planetary motion, which revolutionized our understanding of celestial mechanics.
Johannes Kepler was the first to recognize that configuration,based on his analysis of Tycho Brahe's observational data.

No. Johannes Kepler lived centuries before the invention of Radio. Kepler was the first to recognize that the orbits of the planets were elliptical rather than circular.
It was actually Johannes Kepler who discovered that planets follow elliptical orbits in the early 17th century. Newton later built upon Kepler's work by formulating the law of universal gravitation, explaining the underlying force responsible for the motion of planets.
