Jupiter Bids Farewell to Evening Sky After Sunday Moon Meetup

Jupiter will end its brilliant year-long showing on Sunday evening (June 29) with a rendezvous with a young and slender crescent moon. 

The moon will appear so thin and low that it may be hard to detect in the sun's afterglow, and Jupiter will be just as low, appearing to sit about 12 degrees to the right of the lunar sliver. (Your clenched fist held at arm's length is about 10 degrees wide.)

Indeed, the moon will be only 6 percent illuminated and just 2 1/2 days past new phase. The celestial pair will be setting about an hour after local sunset on Sunday.   

To enhance your chances of getting a view of both moon and planet, make sure that your prospective viewing site has a clear and unobstructed view toward the west-northwest part of the sky. Half an hour after sunset, the moon and Jupiter will hang only about 6 degrees above the horizon. Jupiter will be nothing more than a bright white dot against the twilight background.

You can accentuate your chances of picking up both moon and planet by scanning that part of the sky with binoculars; once you sight them, getting a glimpse of the pair with your unaided eyes should be a bit easier.

Jupiter, the giant of our solar system, is as fascinating as it is photogenic. How much do you know about the king of the planets?

After Sunday, you can pretty much say goodbye to Jupiter as an evening object, as it will be rapidly swallowed up by the sunset glow. The gas giant will be in conjunction with the sun on July 24 and will not reappear again until sometime in mid-August, when it will transition to the early morning sky. 

However, Jupiter is destined to put on a nice showing in the dawn sky on Aug. 18, combining with brilliant Venus to produce 2014's closest conjunction of two planets (and the two brightest planets, no less), making for an attractive celestial scene.

So for Jupiter, this is not "goodbye" but rather "see you later this summer."
