The Moon and Uranus will make a close approach, passing within a mere 47.6 arcminutes of each other. From some parts of the world, the Moon will pass in front of Uranus, creating a lunar occultation. The Moon will be 11 days old.

From Cambridge , the pair will be visible in the evening sky, becoming accessible around 20:19 (EDT), 21° above your south-eastern horizon, as dusk fades to darkness. They will then reach their highest point in the sky at 22:34, 29° above your southern horizon. They will continue to be observable until around 00:51, when they sink below 21° above your south-western horizon.

The Moon will be at mag -12.5; and Uranus will be at mag 5.7. Both objects will lie in the constellation Capricornus.

They will be a little too widely separated to fit comfortably within the field of view of a telescope, but will be visible through a pair of binoculars.

A graph of the angular separation between the Moon and Uranus around the time of closest approach is available here.

The positions of the pair at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 20h50m00s 19°14'S Capricornus -12.5 30'32"5
Uranus 20h48m50s 18°30'S Capricornus 5.7 3"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 148° from the Sun, which is in Leo at this time of year.
