On Sunday evening, revelers can cap their St. Patrick’s Day by enjoying a view of a rendezvous involving two of the brightest objects in the night sky: the moon and the planet Jupiter.

About 45 minutes after sunset on Sunday (March 17), the eye-catching celestial duo will be visible in the southwest sky, roughly two-thirds up from the horizon to the point directly overhead (called the zenith).

The moon will be a wide crescent at the time, 34 percent illuminated by the sun, and will sit below Jupiter. At its closest pass — which will occur at around 10:30 p.m. local daylight time along the U.S. East Coast, and around 7:00 p.m. local time for the West Coast — Earth's natural satellite will be just 2 degrees from the giant planet. (For reference, your clenched fist held at arm's length measures about 10 degrees.)
