Watch the moon pass in front of Uranus today (Dec. 5)

Photo taken in Nagoya, central Japan, on Nov. 8, 2022, shows a lunar occultation of Uranus (seen at the bottom of the moon.)


On Monday (Dec. 5), Uranus will briefly disappear from the night sky when the moon passes in front of the faint planet in an arrangement called a lunar occultation. 

The lunar occultation will start at 12:30 p.m. EST (1730 GMT) when Uranus which will be in the constellation of Aries, begins to vanish behind the moon. At the start of the lunar occultation, Uranus will have a right ascension of 02h52m40s and be around 16 degrees above the horizon, according to In the Sky (opens in new tab). (If you hold out your fist at arm’s length, its width equals around ten degrees in the sky.)
