Venus and Uranus will share the same right ascension, with Venus passing 1°46' to the south of Uranus.
From Cambridge, the pair will be difficult to observe as they will appear no higher than 18° above the horizon. They will be visible in the dawn sky, rising at 03:00 (EDT) – 2 hours and 9 minutes before the Sun – and reaching an altitude of 18° above the eastern horizon before fading from view as dawn breaks around 04:47.
Venus will be at mag -4.3, and Uranus at mag 5.9, both in the constellation Pisces.
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 Uranus 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 45° from the Sun, which is in Taurus 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.
