2021: June – August, Mars Joins Venus

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.
