The Moon and 1 Ceres will make a close approach, passing within 0°02' of each other. The Moon will be 8 days old.

From Cambridge, the pair will be visible in the evening sky, becoming accessible around 17:23 (EST) as the dusk sky fades, 65° above your south-eastern horizon. They will then reach its highest point in the sky at 18:15, 67° above your southern horizon. They will continue to be observable until around 00:51, when they sink below 7° above your western horizon.

The Moon will be at mag -12.0, and 1 Ceres at mag 8.4, both in the constellation Taurus.

The pair 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 1 Ceres around the time of closest approach is available here.

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

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 03h51m20s +20°22' Taurus -12.0 29'37"1
1 Ceres 03h51m20s +20°20' Taurus 8.4 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 99° from the Sun, which is in Capricornus at this time of year.
