Mercury at Western Elongation

   On Saturday March 6th Mercury, the innermost planet, will attain its orbital place generally known as western elongation at 27.3o. At that second Mercury, the Solar, and the Earth, can be organized in one thing near approximating a proper angle as this graphic reveals. Though it sounds complicated, at western elongation for both Mercury or Venus the internal planet shall be to the proper of the Solar as we view them, which means that at western elongation an internal planet rises within the east than the Solar rises. And at japanese elongation with the internal planet on the left aspect of the Solar the internal planet follows the Solar throughout the sky setting after the Solar units.

   From our the orbits of Mercury and Venus seem to maneuver from one aspect of the Solar to the opposite – out to the left (east) from the Solar to japanese elongation, then reverse and transfer westward (inferior conjunction) between the Earth and the Solar to western elongation. From there the internal planet strikes eastward going behind the Solar (superior conjunction) and finally reappearing on the japanese aspect of the Solar for an japanese elongation. Repeat time and again – don’t cease!

   Mercury is presently seen within the morning skies earlier than the Solar rises. This internal planet is steadily shifting previous Jupiter after having handed by Saturn final .
