The Moon and 134340 Pluto will make a close approach, passing within 0°01' of each other. The Moon will be 15 days old.

From Seattle, the pair will be difficult to observe as they will appear no higher than 19° above the horizon. They will be visible between 21:20 and 03:31. They will become accessible around 21:20, when they rise to an altitude of 8° above your south-eastern horizon. They will reach its highest point in the sky at 00:28, 19° above your southern horizon. They will become inaccessible around 03:31 when they sink below 7° above your south-western horizon.

The Moon will be at mag -12.6; and 134340 Pluto will be at mag 15.1. Both objects will lie in the constellation Capricornus.

They will be close enough to fit within the field of view of a telescope, but will also be visible through a pair of binoculars.

A graph of the angular separation between the Moon and 134340 Pluto 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 20h21m50s -23°17' Capricornus -12.6 31'03"4
134340 Pluto 20h21m50s -23°18' Capricornus 15.1 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 166° from the Sun, which is in Cancer at this time of year.
