The Moon and Uranus will make a close approach, passing within a mere 52.8 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 8 days old.

From Fairfield , the pair will become visible at around 18:12 (EST), 64° above your southern horizon, as dusk fades to darkness. They will then sink towards the horizon, setting at 01:11.

The Moon will be at mag -12.0; and Uranus will be at mag 5.7. Both objects will lie in the constellation Aries.

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 02h47m40s 16°42'N Aries -12.0 30'36"4
Uranus 02h49m00s 15°53'N Aries 5.7 3"6

The coordinates above are given in J2000.0. The pair will be at an angular separation of 95° from the Sun, which is in Capricornus at this time of year.
