    Mars - Mercury Question
    From: Brad Morris
    Date: 2013 Feb 2, 20:31 -0800

    Coming up this week, Mars and Mercury will be in close angular proximity to each other. Mercury, of course, is one of the swiftest moving planets in the solar system. Both Mercury and Mars are in the ecliptic plane.

    The question is basic. Can we tell our longitude by the angular separation of the two bodies, similar to a lunar? Can we do this with a sextant? We might be able to tell our longitude using this method, but its below the measurement sensitivity of a sextant.

    Just asking!
