It was Johannes Kepler 1571-1630 who produced the Laws of Planetary Motion in 1618.
He is a danish astronomer who stated that all the planets revolve around the sun in elliptical orbits and that the sun is not in the exact center of the 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.

Yes, every orbit is slightly elliptical ... see - nothings perfect!
Johannes Kepler discovered that planet orbits were elliptical and not circular.

Planets revolve in elliptical orbits due to the gravitational influence of other bodies in the solar system. As planets interact with each other, their orbits can become elongated or slightly off-center, leading to elliptical shapes rather than perfect circles. This is a result of the complex dynamics of the solar system.
Yes, the Earth and other planets in our solar system revolve around the Sun in elliptical orbits due to the force of gravity. This orbital motion is what causes the planets to move in their respective paths around the Sun.
Johannes Kepler proposed the idea that planets revolve around the sun in elliptical orbits in his laws of planetary motion. This idea challenged the prevailing belief at the time that the Earth was the center of the universe.
