    Re: Minimum geocentric Saturn-Mars apparent angular Distance
    From: Antoine Couëtte

    Hello to all,

    As earlier announced, here-below a comparison of our results.

    I have used a method similar to the one published by Jean Meeus in Astronomical Algoritms .

     

    Jupiter / Mars

    Saturn / Mars

    Bill Ritchie

    Ritchie-apr-2020-g47406

    2020-Mar-20 10:37:41

    and 2546.1 arc secs.

    2020-Mar-31 17:31:01

    and 3259.8 arc secs.

    Sean C.

    SeanC-apr-2020-g47392

    10:37:52 UT1 on 20 March, 2020

    2,546 arcseconds

    at about 17:30:30 UT1 on 31 March, 2020

    3,260 arcseconds

    Antoine M. Couëtte

    Couëtte-mar-2020-g47377

    20 March 2020 close to 10:37:21 UT (TT-UT = 69,7 s)

    2,546 arc seconds

    31 March 2020 close to 10:32:15 UT (TT-UT = 69,7 s)

    3,260 arc seconds

    All results are almost the same. And the method derived by Sean is quite efficient !

    Antoine
