The Moon and Uranus will make a close approach, passing within 1°25' of each other. The Moon will be 20 days old.

From Ashburn, the pair will be visible in the morning sky, becoming accessible at around 23:17, when they rise 7° above your eastern horizon. They will then reach its highest point in the sky at 05:31, 66° above your southern horizon. They will be lost to dawn twilight at around 06:15, 65° above your south-western horizon.

The Moon will be at mag -12.1, and Uranus at mag 5.7, both in the constellation Aries.

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

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 02h50m40s +14°27' Aries -12.1 29'41"1
Uranus 02h48m30s +15°46' Aries 5.7 3"6

The coordinates above are given in J2000.0. The pair will be at an angular separation of 110° from the Sun, which is in Leo at this time of year.
