Kepler first noticed that the planets speed up and slow down but cover the same area. This observation led him to propose Kepler's first law of orbital motion, which states that planets move in elliptical orbits with the sun at one of the foci. Therefore, the correct response is:
**The planets speed up and slow down but cover the same area.**
**The planets speed up and slow down but cover the same area.**
