The planets Venus and Neptune will make a close approach, passing within a mere 0.4 arcminutes of each other.
From Ashburn, the pair will be visible in the dawn sky, rising at 04:36 (EDT) – 1 hour and 41 minutes before the Sun – and reaching an altitude of 14° above the eastern horizon before fading from view as dawn breaks around 05:57.
Venus will be at mag -4.1; and Neptune will be at mag 7.9. Both objects will lie in the constellation Aquarius.
They 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 Venus and Neptune around the time of closest approach is available here.
The positions of the pair 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 43° from the Sun, which is in Aries at this time of year.

The circumstances of this event were computed using the DE430 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.
