11/03/2014 – Ephemeris – Mercury is now visible in the morning

November 3, 2014

Ephemeris for Monday, November 3rd.  The sun will rise at 7:22.  It’ll be up for 10 hours and 5 minutes, setting at 5:28.   The moon, 3 days before full, will set at 4:35 tomorrow morning.

When I talk about the planet Mercury I usually use the adjective elusive.  There’s a good reason for that.  Mercury is always close to the sun, being the innermost planet, and it has the most eccentric orbit of all the planets.  Due to our location on the northern hemisphere of the Earth Mercury is best visible on autumn mornings and spring evenings.  These two views, 6 months apart, means that we, at both times are looking at the same part of Mercury’s orbit, but from opposite sides.  The part of Mercury’s orbit we see is the part of its orbit closest to the sun, so the angular separation is not very wide,  19 degrees this elongation.  Observers in the southern hemisphere whose seasons are opposite ours have a much better view. For them Mercury is at its farthest from the sun, and they get elongations of over 25 degrees.

Times are for the Traverse City/Interlochen area of Michigan.  They may be different for your location.
