Five Planets Visible in the Sky

Tonight and tomorrow, the evening sky presents an excellent opportunity to see Saturn. Tonight, you can look for it low in the southwest sky, just to the left of the moon. You should be able to see it without any optics, but a good pair of binoculars or even a modest telescope will provide a feast for the eyes as you should be able to see Saturn's rings!

The Earthsky.org article linked HERE gives instructions for locating Mercury, Mars, Venus, and Jupiter as well. Since the moon is a very small waxing crescent, visibility will be best tonight, good the next two nights as the crescent gets larger and brightens the adjacent sky.

Planets like Saturn shine steadily;  they don't twinkle the way stars do.  The other bright object that you are likely to encounter in this area of the sky is a reddish star, Anatares, the heart of Scorpius.

Antares should definitely appear reddish in your telescope and it twinkles enthusiastically.  It will be to the left of Saturn, with Saturn almost at the mid-point between Antares and the Moon.  If you don't get to view the night sky before the weekend, on Saturday you'll find Antares directly below the moon and Saturn way to the right, forming a triangle.

Four other planets brighten the pre-dawn sky.  The Earthsky.com article gives excellent tips for locating Jupiter, Mars, Mercury, and Venus HERE.  Mars and Jupiter will be next door sky-neighbors this weekend.  They will be the closest they'll be for our viewing for the next three years on Sunday just before dawn.

Jupiter will appear to continue to slide under Mars in the night sky over the weekend.  It will be worth getting up early to see...  they won't be this close again until 2018.
