The Moon and 1 Ceres will share the same right ascension, with the Moon passing 5°45' to the south of 1 Ceres. The Moon will be 23 days old.

From Ashburn (click to change), the pair will be visible in the dawn sky, rising at 00:57 (EDT) – 6 hours and 21 minutes before the Sun – and reach an altitude of 66° above the south-eastern horizon before fading from view as dawn breaks at around 07:01.

The Moon will be at mag -11.6, and 1 Ceres at mag 8.7, both in the constellation Cancer.

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 08h39m50s +17°03' Cancer -11.6 31'53"4
1 Ceres 08h39m50s +22°48' Cancer 8.7 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 72° from the Sun, which is in Virgo at this time of year.
