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 03:15 (EST) – 4 hours and 1 minute before the Sun – and reaching an altitude of 31° above the south-eastern horizon before fading from view as dawn breaks at around 06:55.
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|
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.

The circumstances of this event were computed using the DE405 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).
This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
