From the Wackypedia:

Mercury is the innermost and smallest planet in the solar system, orbiting the Sun once every 88 days….
 
The Romans named the planet after the fleet-footed messenger god Mercury , probably for its fast apparent motion in the twilight sky…. The Hebrews named it Kokhav Hamah, "the star of the hot one" ("the hot one" being the Sun).

The below is from one of my readers -- interesting.  See Numbers 24:17 reference.  In Hebrew, Mercury apparently refers to the coming of Jesus!  If this is true, it is profound re 11-8-06!

I am trying not to get TOO excited..........again.........but its not working. :)
 
Have been searching for the Hebrew meaning of Mercury and came up with KOKHAV.

 Star from Jacob


 
kokhav miya’akov
The Star from Jacob (Num. 24:17). “ I see him, but not now; I behold him, but not near: a star shall come out of Jacob, and a scepter shall rise out of Israel; it shall crush the forehead of Moab and break down all the sons of Sheth.”
 
 
....................Also, did we not read somewhere re Wednesday being a Jewish Wedding day................hmmmm;  this scholar below suggested Wednesday for Mercury as the planets were formed on that day.
 
 
Joseph Klausner (1874-1958), literary scholar and historian, active in reviving the Hebrew language, proposed the audacious idea of naming the days of the week after the planets, as in Roman parlance and in several European languages by which he had been influenced. [5] His proposal was to combine the Hebrew names of the planets with the particle yom, eliding the y: Sunday = Shimshom (day of shemesh, the sun); Monday = Yarhom (day of yar'eah, the moon); Tuesday = Ma'adimom (Ma'adim or Mars day); Wednesday = Kokhavom (Kokhav or Mercury day); [6] Thursday = Tzidkom (after Tzedek, Jupiter); Friday = Noghom (after Noga, or Venus). Saturday would remain Shabbat, since that name recalled Shabtai, the Hebrew name for Saturn.
