Jupiter's Last Evening Dance with the Moon Comes Tonight






                    


Under the southwest sky for a short period after sunset on Thursday, October 11, the young crescent moon will sit 3 degrees toward the bottom right of the bright planet Jupiter. The pair of objects will be visible together in the field of view of the binoculars (orange circle) until they are established shortly after 8 p.m. local time.

		Jupiter will soon finish his brilliant one-year performance in the afternoon sky. October is the last full month in which we will see the giant planet, and tonight, it will meet a crescent and slender moon. The moon will pass some 3 degrees to the top right of the largest planet in the solar system. 

		In fact, the moon itself will appear so thin that, initially, it can be quite difficult to detect in the glare of the sun. The crescent moon will be illuminated by 9% and three days will pass from the new phase. The planet and the moon will settle approximately 1 1/2 hours after sunset. 

		To improve your chances of seeing both the moon and the planet, make sure your viewing site has a very clear and unobstructed view of the west-southwest part of the sky. Half an hour after sunset, the moon and Jupiter will hang about a dozen degrees on the western horizon. As we have pointed out on many other occasions, 10 degrees is approximately equivalent to the apparent width of his closed fist held at arm's length. Then, about half an hour after sunset, the moon will appear a little beyond the horizon. Jupiter will appear under the slender splinter as a bright white dot against the bright twilight background.

		You can increase your chances of collecting both the moon and Jupiter just after sunset if you first scan the western sky with binoculars. Once you see the two bodies, getting a peek of the pair with your lonely eyes should be easier, especially as the twilight deepens.



		Goodbye until winter.

		After tonight, the moon and Jupiter will go their separate ways, with the moon moving to the east while the "king of the planets" will continue to descend every night. During the last week of October, Jupiter will pass near Mercury. But that will be a very difficult pair to observe. Most likely, the low altitude and the bright sky background will prevent you from seeing one or both planets, but if you can catch a glimpse of them, you will have achieved something. 

		For Halloween, you can say goodbye to Jupiter as a night object, since the brightness of the sunset will quickly swallow the planet. 

		Jupiter will be along with the sun, on the opposite side of the Earth star, on November 26. The giant planet will not appear again until the middle or end of December, when it will pass into the morning sky and will again approach Mercury.
