The planet Jupiter, 5th from the Sun and 4th brightest object in the sky, is setting exactly an hour after the Sun. For observing purposes, early July presents the last chance to catch Jupiter in the twilight sky. As the days progress, Jupiter will sink more into the twilight every day. By the middle of the month, the king of the plants will be lost in the Sun's glare. Look for it to reappear in the predawn sky come early August.
