June 30th and July 1st, 2015 - Venus and Jupiter Conjunction

Posted June 30, 2015 11:49 AM by Bayes

The Two Brightest "Wanderers" Meet

The last several weeks, the two brightest planets in the night sky, Venus and Jupiter, have been inching closer to each other in the night sky. At the beginning of June they were 20 degrees apart in the sky. Tonight and tomorrow night Venus and Jupiter will be less than a degree apart, having the appearance of a bright double star in the early evening sky. Here is an article from Sky and Telescope on the conjunction.

Venus and Jupiter: Together at Last

Anyone who pays even cursory attention to the evening sky has surely noticed that the two brightest planets, Venus and Jupiter, have been drawing closer together in the west in the evening twilight. At the beginning of June, the two planets were 20° apart in the sky, about twice the width of your fist held at arm's length. Week by week, Jupiter and the stars behind it have gradually slipped lower in the evening twilight. But Venus, due to its rapid orbital motion around the Sun, has stayed high up.

The resulting slow-motion convergence is setting the stage for a dramatic sky sight. The warm-up act came on June 19th and 20th, when the planetary duo was joined by a thin and lovely crescent Moon. Farther to their upper left, and fainter, was Regulus, the alpha star of Leo. (I was texting all my friends: "Go outside. Now. Look west!") -

Pictures from my neighborhood. Venus and Jupiter Conjunction to the West, Full Moon to the East! The conjunction was better last night (slightly), but it was partly cloudy and I didn't have my camera when it was clear enough to see. Tonight wasn't bad though.

Pretty awesome ! Is this one of those "once in a lifetime event" (that then repeats 3 or 4 times in less than 20 years) ?

Yes and no. Each one is a little different. Sometimes in the morning, sometimes farther apart. Still, the general event does occur relatively frequently.
