Venus and M44 will make a close approach, passing within 1°10' of each other.
From Ashburn, the pair will be visible in the dawn sky, rising at 03:55 (EST) – 2 hours and 43 minutes before the Sun – and reach an altitude of 25° above the eastern horizon before fading from view as dawn breaks at around 06:20.
Venus will be at mag -4.0, and M44 at mag 3.1, both in the constellation Cancer.
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 M44 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 coordinates above are given in J2000.0. The pair will be at an angular separation of 31° from the Sun, which is in Leo 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.
