Question
how did kepler describe the planets orbits?
the planets orbits are circular
the planets orbits are elliptical
the planets and the sun orbit earth
the planets have miniature orbits called epicycles
Kepler's first law of planetary motion states that the planets move in elliptical orbits with the Sun at one focus. This is a fundamental concept in astronomy. The idea of circular orbits was a previous incorrect assumption (e.g., in the Ptolemaic and early Copernican models). The statement that planets and the Sun orbit Earth is a geocentric view (like the Ptolemaic model) which was disproven. The concept of epicycles was part of the Ptolemaic model to explain retrograde motion of planets in a geocentric framework and is not in line with Kepler's laws.
