    Re: How far is polaris?

    I am getting quite confused with various astronomical measurements for
    polaris. According to wikipedia, polaris is:-
    430 lightyears,
    132 parsecs (seconds of parallax = 2.2minutes!)
    2400 Astronomical units
    and has a Parallax (�)  7.56 � 0.48 mas
    Now as far as I can see, not all of these can be correct, but since
    several sources on the web quote the distance as 132 parsecs, or 132
    seconds of wobble = 2.2minutes, I think this probably has a grain of
    truth in it.
    QED the position of Polaris will wobble by around a second of arc as
    the year progresses which is precisely what I said a few posts ago -
    and something which nobody seems prepared to admit (so clearly I must
    have got it wrong!)
