The Moon and 136199 Eris will share the same right ascension, with the Moon passing 8°17' to the north of 136199 Eris. The Moon will be 25 days old.

From Ashburn (click to change), the pair will be visible in the dawn sky, rising at 03:07 (EDT) – 2 hours and 37 minutes before the Sun – and reach an altitude of 24° above the south-eastern horizon before fading from view as dawn breaks at around 05:23.

The Moon will be at mag -11.3 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 01h45m00s +06°05' Pisces -11.3 32'20"2
136199 Eris 01h45m00s -02°11' Cetus 18.8 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 61° from the Sun, which is in Taurus at this time of year.
