Venus and 1 Ceres will share the same right ascension, with Venus passing 3°04' to the south of 1 Ceres.

From Fairfield, the pair will be visible in the dawn sky, rising at 03:17 (EST) and reaching an altitude of 32° above the south-eastern horizon before fading from view as dawn breaks around 06:57.

Venus will be at mag -4.5, and 1 Ceres at mag 8.9, both in the constellation Libra.

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 Venus 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
Venus 15h17m30s -14°41' Libra -4.5 27"0
1 Ceres 15h17m30s -11°37' Libra 8.9 0"0

The coordinates above are given in J2000.0. The pair will be at an angular separation of 46° from the Sun, which is in Sagittarius at this time of year.
