Question 1142988
The semi-major axis a is half of the greatest width of the ellipse.
:
a = 185.8/2 = 92.9 million miles
:
Linear eccentricity c - is the distance from the focal point to the center of the ellipse
:
c = 1.58 million miles
:
Eccentricity of ellipse e is the ratio of the linear eccentricity c to the length of the semi-major axis a
:
e = c/a = 1.58/92.9 = 0.017
:
***************************************************************************
The greatest distance(Apogee) of Earth from the sun is
:
A = a * (1+e) = 92.9 * 1.017 = 94.4793 is approximately 94.48 million miles
:
The least distance(Perigee) of Earth from the sun is
:
P = a * (1-e) = 92.9 * 0.983 = 91.3207 is approximately 91.32 million miles
