The Moon and 134340 Pluto will make a close approach, passing within 0°05' of each other. The Moon will be 11 days old.

From Ashburn, the pair will be visible in the evening sky, becoming accessible around 20:28 (EST) as the dusk sky fades, 16° above your south-eastern horizon. They will then reach its highest point in the sky at 23:18, 28° above your southern horizon. They will continue to be observable until around 03:15, when they sink below 7° above your south-western horizon.

The Moon will be at mag -12.5; and 134340 Pluto will be at mag 15.0. Both objects will lie in the constellation Sagittarius.

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 19h32m00s -22°07' Sagittarius -12.5 29'53"1
134340 Pluto 19h32m00s -22°13' Sagittarius 15.0 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 151° from the Sun, which is in Leo at this time of year.
