The Earth revolves around the Sun along an ellipse. The Sun lies in the
focus of the ellipse. The largest distance from the Sun to the Earth is 152.1
million kilometers, and the shortest is 147.1 million kilometers. Find the
length of the semi-minor axis of the ellipse and the eccentricity of the el-
lipse. What is the distance between the two foci of the ellipse?

Step-by-step explanation:
The sum of the distances to any point on the ellipse (x,y) from the two foci (c,0) and (-c,0) is a constant. That constant will be 2a. If we let d1 and d2 bet the distances from the foci to the point, then d1 + d2 = 2a
