Consider a GTO orbit (see Wikipedia article on GTO) with the perigee just outside the Earth's atmosphere at an altitude of 622km and apogee near the GEO orbit at an altitude of 35,786km. Assume that the Earth's radius is RE = 6378km. All orbits around a single large body are elliptical (it is called a two-body problem and you will learn about it in orbital mechanics). Furthermore, the center of the large body is at one of the foci of the ellipse. The semi-major axis can be calculated by averaging the distance of the perigee and apogee from the center of the Earth. What is the semi-minor axis (in km)? 2b 2c 2a

Step 1
From the figure,
Now, the distance between the two foci can be obtained by subtracting the distance between perigee and center of the earth from the distance between the apogee and the center of the earth.
