Look up at the night sky on January 10 to see a rare ‘triple conjunction’ of planets, as Jupiter, Saturn, and Mercury form a tight triangle in the sky. The best time to see this phenomenon will be around 45 minutes after sunset on Sunday, by looking low in the sky toward the southwest horizon. While you won’t need to borrow star-watching equipment from the Mauna Kea Observatories to see the triple conjunction, a pair of home binoculars will definitely help you to see these planets form a tight bud just 1.6° apart. To have something to compare the conjunction to, it’s a good idea to look up in the evenings before and after January 10 too. That way, you’ll be able to track this planetary trio as they move in close together, and then apart.
