The young crescent Moon’s nightly motion from 31 December 2016 to 3 January 2017 carries it past dazzling planet Venus and first-magnitude Mars. A small telescope also reveals outermost planet Neptune, which passes just 0.02 degrees from Mars around 7h UT on 1 January, offering observers around the world a New Year’s Day treat.
Find a location that offers you an unobstructed view of the horizon from south to southwest an hour after sunset. With clear skies, you’ll be able to follow Venus and Mars from night to night on their celestial peregrinations through the constellations of Sagittarius and Capricornus. The two planets almost keep pace with each other throughout the remainder of November.

We show you how to locate Neptune with binoculars and small telescopes.
