For the first time in almost a decade, sky-watchers this week will be able to see all five naked-eye planets over the course of one night for several nights in a row.
The classical naked-eye planets—Mercury, Venus, Mars, Jupiter, and Saturn—can be seen easily without optical aids and so have been known since ancient times. But the quintet hasn’t appeared together during a single night since 2004.
What’s more, this week’s parade of planets will be joined in the nighttime skies by the waxing crescent to waxing gibbous moon and the superbright stars Sirius and Canopus…
Although the moon and the seven bright objects will all be visible in one night, they won’t all appear at the same time or in the same region of the sky.
The best time to catch sight of the cosmic parade will be between February 28 and March 7. This is when the more elusive planets Mercury and Mars will be at their brightest in the evening sky for 2012, and when the moon will be above the horizon for many hours before setting…
“The moon, of course, is our closest cosmic neighbor and the only one we can really study as a world with the naked eye or even simple binoculars…However these other points of light are all really bright objects in the sky too, so to get the full experience, take your time and let your eyes adapt to the darkness and enjoy..” said Geza Gyuk, an astronomer with the Adler Planetarium in Chicago.
RTFA for suggestions in where to look and when. Enjoy. I hope you live somewhere with little light or no pollution.
Sorry, Northern Hemisphere only. :)
