Back in Early June, Mercury, Venus, and Jupiter were involved in a cosmic dance in the early evening sky known as a planet conjunction.
A conjunction is when two or more astronomical objects appear close to one another from the standpoint of a third observer. It’s a dynamic byproduct of orbital mechanics. There are many different kinds of conjunctions; you can literally use any astronomical objects; the moon and a planet, the sun and a planet, two planets, a planet and a distant star, etc. Obviously, this conjunction, seen in the shape of a triangle off center-left, features Jupiter (top left point), Venus (bottom center point), and Mercury (top right point).
This image in particular was taken by Mike Dillnger just after sunset on May 26 from the Haleakala Summit in Maui, Hawaii.
