Mars and Jupiter – A Close Pair for Early Risers

October 17th, 2015

The dance of the planets continues in the pre-dawn sky as Mars and Jupiter form a close pair in the twilight. With the distance between them being less than the width of a full Moon, this is an excellent opportunity to witness an event that only occurs once every couple of years. In fact, if you miss it, you’ll have to wait until January 6th 2018 to catch the planets again in the pre-dawn sky. As a consolation, on that date they’ll be even closer with just half the distance separating them. (And it’ll be a Saturday on that date too!)
