orbit  
my question is whether there could be sattelite orbits that dont include a cross-section of the earth that involve its center (that is how all the sattelite orbits apear in the illustration) i added a picture of an orbit and im wodering whether that couyld be stable thanks

Answer
Hi, Itamar, thanks for writing.  The orbit you showed, if orbiting around the Lagrange Point 2, where the centrifugal force on the point is equal from both the Sun and Earth, would work.  There is also a Lagrange point 1 on the Sun side of the earth that something can orbit around, where the Sun's gravity and Earth's is equal.  Also are points on the opposite side of the Sun and ahead or behind the Earth's orbit at Earth's distance from the Sun.  See http://en.wikipedia.org/wiki/Lagrangian_point.  Write anytime!
