The illustration was made using LaTeX and tikz using the following code:
\begin{tikzpicture}[scale=.4] \begin{scope} \draw[fill=blue!25,rotate=-23.5] (0,0)circle (.63781 and .63568); \draw[gray,ultra thin,dashed](0,-.7)--++(0,1.6); \draw (0,0) ++(90-23.5:.8)--++(90-23.5:-1.6); \begin{scope}[rotate around={5.14:(0,0)}] \draw[<->] (.75,0)--++(38.22,0)node[above,midway,rotate=5.14]{384 400 km}node[below,midway,text=gray,rotate=5.14]{\footnotesize{Perigee: 363 300 km. Apogee: 405 500 km}}; \draw (.63781+38.44+.1736,0) coordinate (moon); \end{scope} \draw[fill=gray] (moon) circle (.1736 and .1738); \draw[->,gray] (30,0)arc(0:5.14:30)node[midway,right]{5.14$^\circ$}; \draw[ultra thin,gray](.75,0)--++(37.6,0)node[midway,below]{Ecliptic plane}; \end{scope} \end{tikzpicture}
