    Not to be a spoilsport, but... photo? That's  just a bit of digital art,
    isn't it? A fantasy world with a giant moon, a  distant sun, and an unknown sea.
    Pretty, yes. But fantasy.
    
    Be thankful  the Moon (the real Earth's moon) is only half a degree wide in
    our skies. If it  were close enough to appear even two degrees wide, the ocean
    tides would rise  and fall with an average range of about 200 feet. The
    tide-generating  acceleration is proportional to the mean density of the
    tide-producing object  and also proportional to that object's apparent angular diameter
    cubed (2  degrees is 4x bigger, so tides 64x larger in range).

    42.0N 87.7W,  or 41.4N 72.1W.
