How much of the planet's surface can the alien see if she is in
    the middle of one of the faces?<br />
    What about on one of the edges? <br />
    Or at a vertex?<br />
     <br />
    Try to picture a route around the planet either in three
    dimensions or on a net. Can you be sure every point on the
    surface is visible from your route? Can you make a more
    efficient route? Some diagrams might help!<br />
