Kepler noticed that most planets have highly elliptical orbits, which means that their orbits are not perfectly circular. This observation led him to propose Kepler's first law of orbital motion. To arrive at this answer, one can examine Kepler's findings and understand the characteristics of planetary motion. Specifically, Kepler's first law states that planets move in elliptical orbits around the Sun, with the Sun located at one of the elliptical foci. By studying the patterns and shapes of planetary orbits, Kepler discovered that they are not perfectly circular, but rather elongated and elliptical in shape. This breakthrough observation about the nature of planetary motion led to the formulation of the first law.
