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."

∙ 9y agoIt was Johannes Kepler who published his new model of the planets' orbits in 1609.
He was aiming to describe the planets' positions as measured in a new set of observations by Tycho Brahe using new equipment with greater accuracy than ever before.
Kepler took the idea of placing the Sun at the centre from Copernicus's earlier model, but he found that the planets' positions could be modelled more accurately by using the novel idea of elliptical orbits.
Accuracy of the predicted positions was the only reason, at the time, to think that Kepler's model was better than the earlier ones. They would use the new model to make predictions on a certain date for all the planets, and on that date they would find that the planets were where they should be.
However after later discoveries by Isaac newton and others it was understood that the elliptical orbit is a natural consequence of the force of gravity from the Sun, which was and is far more massive than any of the planets.
Today Kepler's model is the basis for all calculations for objects in the solar system, with tiny corrections from Einstein's General Theory of Relativity.

Who is the astronomer who discovered planets follow elliptical orbit?
discovered follow
What early astronomer discovered why planets stay in their orbits?
Newton
What astronomer discovered that the orbits of the planets are elliptical rather than round?
Johannes Kepler.
What do astronomer's now believe about Pluto's affect on Neptune's orbit?
They believe that Pluto's orbit throws Neptune's off,so every 20 out of 250 years,Neptune is the outermost of the Planets.

Astronomer who discovered that planets orbit in an ellipserather than a perfect circle?
Kepler
What early astronomer discovered why planets stay in orbit?
Nicolaus Copernicus discovered why planets stay in orbit when he found that the planets revolve around the sun. He is credited with starting the Scientific Revolution through this discovery.
