The First Artificial Satellite to Orbit Earth Was Sputnik I $$x = 211 \mathrm {~km} , y = 943 \mathrm {~km}$$

The first artificial satellite to orbit Earth was Sputnik I (launched by the former Soviet Union in 1957) .Its highest point above Earths surface was 943 kilometers,and its lowest point was 211 kilometers (see figure) .The center of Earth was at one focus of the elliptical orbit,and the radius of Earth is 6392 kilometers.Find the eccentricity of the orbit.Round your results to four decimal place.​ ​ $$x = 211 \mathrm {~km} , y = 943 \mathrm {~km}$$ ​

A) Eccentricity: $e \approx 0.4555$
B) Eccentricity: $e \approx 0.4755$
C) Eccentricity: $e \approx 0.4955$
D) Eccentricity: $e \approx 0.4355$
E) Eccentricity: $e \approx 0.5155$
