Evaluate as true or false: Kepler's first law states that the Sun is at the center of a planet's elliptical orbit.

Kepler's first law, also known as the Law of Orbits, actually states that the paths of the planets around the Sun are ellipses, with the Sun located at one of the two foci of the ellipse, not at the center. This distinction is crucial because it highlights that while the Sun is at a focal point of the elliptical orbit, it is not positioned at the ellipse's center. This understanding is foundational in celestial mechanics and showcases the non-circular nature of planetary orbits as established by Kepler's observations. Therefore, the assertion that the Sun is at the center of a planet's elliptical orbit is false.
