The Moon and Uranus will make a close approach, passing within 1°02' of each other. The Moon will be 18 days old.

From Ashburn, the pair will be visible in the morning sky, becoming accessible around 21:58, when they rise to an altitude of 7° above your eastern horizon. They will then reach its highest point in the sky at 03:44, 58° above your southern horizon. They will be lost to dawn twilight around 06:21, 42° above your south-western horizon.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

The Moon will be at mag -12.6; and Uranus will be at mag 5.7. Both objects will lie in the constellation Pisces.

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 01h15m00s +06°06' Pisces -12.6 32'59"7
Uranus 01h13m50s +07°06' Pisces 5.7 3"6

The coordinates above are given in J2000.0. The pair will be at an angular separation of 139° from the Sun, which is in Leo at this time of year.
