{2013 Sky Observer Guide} Triple Conjunction of Planets

This year’s May and June is the time of rare plan­e­tary dances. 

The three bright­est planets–Venus, Jupiter, and Mercury–are seen above the hori­zon togeth­er, and on May 26 the sun­set is going to be even more spec­tac­u­lar, when these plan­ets will gath­er to form a bright tri­an­gle only three degrees wide.

The plan­ets will all be vis­i­ble at a 10-degree angle. The best time to look is about 30 to 60 min­utes after sun­set. The three plan­ets will be close to the hori­zon, so a clear view of the west­ern sky is essen­tial. The tri­an­gle will be seen even in places with heavy urban light pol­lu­tion.

The tri­an­gle begins to dis­perse on May 27th, but on May 28th, Venus pass­es Jupiter at a dis­tance of 1 degree, form­ing a tru­ly remark­able pair.

But the show is far from over.

Venus, Jupiter and Mer­cury will begin to arrange them­selves so that by June 5, 2013, they will be in a line.
