    "According to WIkipedia polaris is at "2400 Astronomical units"."
    
    The moral of that story is-don't believe what you read in Wikipedia.
    
    "However, wikipedia gives the Parallax (�) is given as  7.56 � 0.48
    mas (minutes of arc),"
    
    No. mas means milli-arc-seconds. The distance of Polaris, 430 light years, 
    corresponds to that arc.
    
    "so clearly I can't be like some and assert I
    fully understand the subject."
    
    Only too true, I fear.
    
    George.
