Several news outlets are reporting that Jupiter will be so close to earth this month that its moons can be seen with binoculars. This is supposed to occur in the middle of the month. - WOFL Fox 35
I was just thinking about @Hal Pollner when I heard that Jupiter will be in opposition on the 10th of June. We won't see it here, as there is too much daylight, but I'll bet it will be quite spectacular through a telescope in southern California.
Jupiter has 79 confirmed moons orbiting the giant planet. The four large "Galilean Moons" (Io, Europa, Ganymede, and Callisto) are easy to see with binoculars, although 1 or 2 of them may be behind the planet at any time. It's best to view them when our Moon isn't in the sky. A 6" Meade Computerized Refractor like this will pull the eyes right out of your head! (And the cash right out of your wallet!) Hal
