See explanation.

Explanation:

This #Law# of #Nature# was enunciated by Johannes Kepler (1571-

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.
