This statement is a simplified description of the motion of planets in the solar system. According to Kepler's laws of planetary motion, planets move in elliptical orbits around the Sun. The Sun is located at one of the foci of the ellipse. The other focus is empty and does not contain any significant mass.
An ellipse is a geometric shape with two foci, and the sum of the distances from any point on the ellipse to the two foci is constant. In the case of planets orbiting the Sun, the Sun is located at one of the foci, and the other focus is empty.
The orbits of planets are not perfect circles but instead slightly elongated ellipses. This means that at certain points in their orbits, planets are closer to the Sun (perihelion) and at other points, they are farther away (aphelion).
The statement accurately describes the general motion of planets around the Sun, highlighting the elliptical nature of their orbits and the position of the Sun at one of the foci.
