The Moon and 136199 Eris will share the same right ascension, with the Moon passing 8°12' to the north of 136199 Eris. The Moon will be 19 days old.

From Ashburn (click to change), the pair will be visible in the morning sky, becoming accessible at around 22:25, when they rise 7° above your eastern horizon. They will then reach its highest point in the sky at 03:40, 48° above your southern horizon. They will be lost to dawn twilight at around 06:27, 33° above your south-western horizon.

The Moon will be at mag -12.6 in the constellation Pisces, and 136199 Eris at mag 18.8 in the neighbouring constellation of Cetus.

A graph of the angular separation between the Moon and 136199 Eris around the time of closest approach is available here.

The positions of the two objects at the moment of conjunction will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 01h44m40s +05°50' Pisces -12.6 31'53"7
136199 Eris 01h44m40s -02°21' Cetus 18.8 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 140° from the Sun, which is in Leo at this time of year.
