Which of the following choices correctly describes the orbital relationship between earth and the sun?
a. the sun orbits earth in a perfect circle
c. the sun orbits earth in an ellipse, with earth at one focus
b. earth orbits the sun in a perfect circle
d. earth orbits the sun in an ellipse, with the sun at one focus

I think the correct answer from the choices listed above is option D. The orbital relationship between earth and the sun would be that the earth orbits the sun in an ellipse, with the sun at one focus. Hope this answers the question. Have a nice day.

d. earth orbits the sun in an ellipse, with the sun at one focus

Explanation:

The planetary oscillation of the earth around that of the sun shows a relationship where the sun gravity attracts the earth and the earth moves in an elliptical orbit and has the earth is tilted the sun rays fall incline on the earth and hence all this is due to the gravitational and rotational axis of the earth and sun.Studied by the ptolemy and his followers.
