Ellipse
No. While Kepler made major advancements in the proposal, the first person to formally propose that the planets orbit the sun was Copernicus.
The planetary orbits of our solar system are considered "elliptical." This includes "circular" orbits, as a circle is a type of ellipse. In astrodynamics, an elliptical orbit and a circular orbit both fit into the description of a Kepler Orbit.

Johannes Kepler determined that all planets have elliptical orbits.
Johannes Kepler proposed that these planets orbit the sun in ellipses, not circles. That is why we have Kepler's Law of Planetary Motion.

Why the planets stayed int their orbit.
Johannes Kepler did that first.
Kepler discovered the orbits of the solar system are elliptical.
