The Moon and 1 Ceres will share the same right ascension, with the Moon passing 4°56' to the south of 1 Ceres. The Moon will be 26 days old.

From Ashburn (click to change), the pair will be visible in the dawn sky, rising at 03:02 (EDT) – 3 hours and 25 minutes before the Sun – and reach an altitude of 33° above the eastern horizon before fading from view as dawn breaks at around 06:08.

The Moon will be at mag -10.4, and 1 Ceres at mag 8.9, both in the constellation Gemini.

The pair 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 1 Ceres 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 07h10m10s +19°12' Gemini -10.4 32'37"0
1 Ceres 07h10m10s +24°09' Gemini 8.9 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 39° from the Sun, which is in Leo at this time of year.
