February 11th 2019

On the evenings surrounding Tuesday, February 12, Mars’ faster eastward orbital motion will carry it closely past Uranus, which will be more than 12 times farther away from Earth. Their smallest separation of only 1 degree (a finger’s width) will happen on Tuesday evening, when the red and blue planets will appear together in the eyepiece of a backyard telescope at low magnification. While much brighter Mars will be north (to the upper right) of Uranus, your telescope might flip the view. (Use the nearby moon to test how your telescope alters the view.)
