Question

the moon is a sphere with a radius of 567 km. determine an equation for the ellipse if the distance of the satellite from the surface of the moon varies from 900 km to 169 km

Answer 1

a=567 km+900 km
a=1,467 km

b=567 km+169 km
b=736 km

x^2/a^2+y^2/b^2=1
x^2/(1,467)^2+y^2/(736)^2=1

Please, see the graph in the attached graph.

Thanks.
