Astronomy Tonight: Mercury, Venus, Mars and Moon

Tonight the moon will join Mercury, Venus and Mars. Again, you'll need a very low horizon. If you live along the west coast, this is a perfect time to head for the beach.

About half an hour after sunset, look just above the western horizon for the moon. Mercury, Venus and Mars will be just to its upper right. You'll need binoculars to see all three planets if it's not dark enough. And don't wait too late or the planets and the moon will sink below the horizon.
