The Moon and Uranus will make a close approach, passing within 1°41' of each other. The Moon will be 22 days old.

From Washington, the pair will be visible in the dawn sky, rising at 00:52 (MST) and reaching an altitude of 61° above the south-eastern horizon before fading from view as dawn breaks around 06:20.

The Moon will be at mag -11.6, and Uranus at mag 5.8, 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 02h50m30s +14°10' Aries -11.6 29'36"1
Uranus 02h48m00s +15°44' Aries 5.8 3"5

The coordinates above are given in J2000.0. The pair will be at an angular separation of 84° from the Sun, which is in Cancer at this time of year.
