Explanation:
This
1630). Under the gravitational attraction, the central attracting space
body ( star/planet ) exerts a centripetal force that is inversely
proportional to the square of the distance of the attracted body (
planet/satellite ). By astute mathematical calculations, it was proved
that the orbiters governed by this central force move in an ellipse.
The center of the attracting body is a focus of this ellipse.
So, the Earth moves around its star Sun along an elliptic orbit, with
the center of the Sun as a focus of the elliptic orbit.
