A spectacular gathering of three bright planets and a lovely waning crescent moon will be the chief celestial attraction in the predawn sky this weekend, with the moon, Venus, Mars and Jupiter all making an appearance. It will, in fact, be possible for anyone with a clear and unobstructed view of the southeast sky to see this foursome in a single glance.

The trio Venus, Mars and the moon will be visible to crowd into a relatively tiny spot in the sky, on Saturday. The moon is going to be aligned with the amazing Venus, and quite dimmer Mars.

The moon will be shining less than 2 degrees to the right of Venus on Saturday morning. Meanwhile, the pumpkin-colored Mars, will glow above the brilliant moon and Venus. The Red Planet will be shining with just 1/250th of the Venus' intensity.

The weekend's moon-and-planet sky show actually started early November 6. In clear weather sky-gazers had the opportunity to get a glimpse of Jupiter in the southeastern sky, by sitting just to the left and bit above the crescent moon.

Every year, a wide variety of different conjunctions and configurations that involve the moon and planets occurs normally. However, it is quite unusual, when 3 or more bright planets plus the moon come together and exist in the same small part of the sky.
