5. The Night Sky May 24: Venus, Jupiter, and Mercury now all fit within a 5° circle. That means you could cover them with a golf ball held at about arm's length. And you can view all three at the same time in most binoculars. They'll stay within a 5° circle until May 29th. May 26: The grouping is now tightest; all three planets fit in a 2½° circle, forming a striking little triangle. Your thumb at arm's length will just about cover them. May 27: Jupiter appears right next to Venus. After this, Jupiter pulls down and right of Venus and Mercury, disappearing from view in early June. May 28 and afterward: Mercury, meanwhile, is coming into its own. It's entering its best evening showing of 2013, soaring ever higher above Venus until about June 7th. At that point it slowly begins to sink back toward Venus and also starts fading — slowly at first, then increasingly fast after mid-June. Sky & Telescope
