The Moon and 1 Ceres will make a close approach, passing within 0°28' of each other. The Moon will be 23 days old.

From Cambridge, the pair will be visible in the dawn sky, rising at 23:46 (EST) and reaching an altitude of 62° above the south-eastern horizon before fading from view as dawn breaks around 05:59.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

The Moon will be at mag -11.6, and 1 Ceres at mag 8.8, 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 05h44m50s +21°01' Taurus -11.6 29'45"6
1 Ceres 05h44m40s +20°33' Taurus 8.8 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 80° from the Sun, which is in Leo at this time of year.
