    Planetary Corrections
    From: Bob Goethe
    Date: 2020 Nov 28, 08:49 -0800

    On page A2 of the Nautical Almanac for 2021 are "Additional Corrections" for Mars and Venus.

    • Are there ever years where there are "Additional Corrections" for planets other than Mars and Venus?
    • In 2021, all of the "Additional Corrections" are to be added.  Could there ever be years when some of the corrections are to be subtracted?

    Thanks,

    Bob
