Johannes Kepler's work in astronomy mainly dealt with:

**b. Their orbiting motion and the shape of the orbital paths.**

Kepler is best known for his three laws of planetary motion, which describe how planets move in elliptical orbits around the sun, the relationship between the time a planet takes to orbit the sun and its distance from the sun, and the rate at which planets sweep out areas in their orbits.
