This evening brilliant Venus and Mercury continue their planetary display in the western sky, Mercury reaches its greatest separation (elongation) from the sun tomorrow evening. Both planets are emerging from their solar superior conjunctions. After it reaches its greatest elongation, Mercury quickly returns to the sun’s glare and moves into the morning sky.
Venus is in the sky until October.
On March 18, Mercury passes Venus again as the waxing crescent moon joins the planetary pair in the western sky.
This evening Mercury is 4 degrees to the upper right of Venus.
