Calculates the angular separation between the Sun and the given body.
Returns the full angle seen from
the Earth, between the given body and the Sun.
Unlike PairLongitude, this function does not
project the body's "shadow" onto the ecliptic;
the angle is measured in 3D space around the plane that
contains the centers of the Earth, the Sun, and body.
