01/10/2014 – Ephemeris – Venus will pass inferior conjunction with the sun tomorrow.

January 10, 2014

Ephemeris for Friday, January 10th.  The sun will rise at 8:18.  It’ll be up for 9 hours and 4 minutes, setting at 5:22.   The moon, 3 days past first quarter, will set at 4:19 tomorrow morning.

Tomorrow what has been our evening star during summer an autumn will pass between the Earth and the Sun and will enter the morning sky, where sharp-eyed observers will pick it up just before sunrise.  That passage is called inferior conjunction, because Venus moves between the Earth and the Sun.  Venus and Mercury are called inferior planets, not because of their quality, but because they orbit inside the earth’s orbit.  Mars through Neptune are then of course superior planets.  The last time Venus passed inferior conjunction, on June 5th, 2012 it passed directly in front of the sun in a rare transit.  This time it will be north of the sun by about 5 angular degrees.   There’s only a hundred and four years before the next transit.

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

Addendum
