May 28, 2021: This evening Mercury passes brilliant Venus for the second of three conjunctions during this evening apparition of the second planet from the sun. Use a binocular about 45 minutes after sunset to see the speedy planet 0.4° to the lower left of Venus. This is the closest visible conjunction until 2033.
April 25, 2021: Mercury passes Evening Star Venus this evening after sunset. Look low in the western sky about 20 minutes after sunset. Mars is marching eastward in Gemini, near the star cluster Messier 35. The bright moon is near Spica.
Still low in the sky during brighter twilight, brilliant Venus moves through Cancer and Leo. Mars enters the scene (within 10°) as it moves toward its solar conjunction. As the ecliptic’s angle with the western horizon decreases, the Venusian setting time interval shrinks several minutes until late August. Venus passes the Red Planet (July 12) and Regulus (July 21). A binocular is needed to make observations of conjunctions with the dimmer stars.
