You can put this solution on YOUR website!
Not knowing when those 73 days occur,
\n" ); document.write( "we can give only an approximate average,
\n" ); document.write( "but it does not matter because we are not astrophysicists,
\n" ); document.write( "expected to know the exact period of Earth
\n" ); document.write( "(about 365.25 days, but variable), and
\n" ); document.write( "according to Kepler's laws of planetary motion, in equal times
\n" ); document.write( "that line sweeps equal area sectors of Earth's elliptical orbit (not equal angles).
\n" ); document.write( "For math class purposes (but don't say that to your space science teacher),
\n" ); document.write( "Earth does one turn, $\"2pi\"$ $\"radians\"$ , around the sun in $\"365days\"$ ,
\n" ); document.write( "at a constant angular velocity of.
\n" ); document.write( " $\"2pi%2F365\"$ radians per day.
\n" ); document.write( "In $\"73+days\"$ , the angle swept would be
\n" ); document.write( " $\"2pi%2A73%2F365\"$ $\"radians=0.4pi\"$ $\"radians=about1.257\"$ $\"radians\"$ . \n" ); document.write( "
