Johannes Kepler developed the laws of planetary motion.
However he was German not Austrian.
The Austrian scientist you are referring to is Johannes Kepler. Although he was German by birth, Kepler spent a significant part of his career in Austria. He is best known for formulating the three laws of planetary motion, which describe how planets orbit the sun in elliptical paths, with varying speeds, and in relation to their distance from the sun.

The Austrian scientist who developed laws describing the motion of planets is Johannes Kepler. Although he was born in what is now Germany, he worked in Austria and formulated the three laws of planetary motion in the early 17th century. These laws describe the elliptical orbits of planets, the relationship between a planet's orbital period and its distance from the Sun, and the areas swept out by a planet as it orbits. Kepler's work laid the foundation for modern astronomy and greatly advanced our understanding of planetary motion.
