Visit an aquarium, planetarium, and natural history museum—all under one living roof.
The littlest planet always leads hopeful skywatchers on a merry chase, darting from one side of the Sun to the other and switching off between the early evening and predawn skies every few weeks. At the beginning of July, it is separating from the Sun and entering the evening sky, although this is not a favorable apparition for observers in the northern hemisphere because of the shallow angle of the planets' path against the stars with respect to the horizon keeps Mercury from getting very high above the horizon, even when it reaches greatest eastern elongation on July 30.
Will you be able to see the Moon pass nearby, low in the west just after sunset on the evenings of July 24 and 25, when Mercury and the star Regulus (the heart of Leo the Lion) are close together? As Mercury retreats back toward the Sun, its encounter with the Moon on the 21st will be lost in the glare, and after reaching inferior conjunction on August 26, Mercury crosses back over to the predawn sky. It has a spectacular clustering low in the east with Mars, Venus, and the star Regulus from September 10-16, followed by a morning meeting with the Moon on the 18th.
