function deg = km2deg(km)
%KM2DEG Convert distance from kilometers to degrees
%
%   DEG = KM2DEG(KM) converts distances from kilometers to degrees as
%   measured along a great circle on a sphere with a radius of 6371 km, the
%   mean radius of the Earth.
%
%   DEG = KM2DEG(KM,RADIUS) converts distances from kilometers to degrees
%   as measured along a great circle on a sphere having the specified
%   radius. RADIUS must be in units of kilometers.
%
%   DEG = KM2DEG(KM,SPHERE) converts distances from kilometers to degrees,
%   as measured along a great circle on a sphere approximating an object in
%   the Solar System.  SPHERE may be one of the following strings: 'sun',
%   'moon', 'mercury', 'venus', 'earth', 'mars', 'jupiter', 'saturn',
%   'uranus', 'neptune', or 'pluto', and is case-insensitive.
