The Moon and Uranus will make a close approach, passing within 1°14' of each other. The Moon will be 15 days old.
From Cambridge , the pair will be visible in the morning sky, becoming accessible around 20:28, when they reach an altitude of 21° above your eastern horizon. They will then reach their highest point in the sky at 01:27, 62° above your southern horizon. They will be lost to dawn twilight around 05:55, 27° above your 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 Aries.
They will be too widely separated to fit 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 | 02h44m50s | 14°12'N | Aries | -12.5 | 29'40"0 |
| Uranus | 02h42m50s | 15°21'N | Aries | 5.7 | 3"7 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 165° from the Sun, which is in Virgo at this time of year.
