Venus and Jupiter will make a close approach, passing within 1°01' of each other.

From Fairfield, the pair will be visible in the dawn sky, rising at 03:21 (EDT) – 3 hours and 57 minutes before the Sun – and reaching an altitude of 39° above the south-eastern horizon before fading from view as dawn breaks around 07:00.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

Venus will be at mag -4.4; and Jupiter will be at mag -1.8. Both objects will lie in the constellation Leo.

They will be too widely separated to fit within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars.

At around the same time, the pair will also share the same right ascension – called a conjunction.

A graph of the angular separation between Venus and Jupiter 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
Venus 11h06m50s +05°39' Leo -4.4 24"1
Jupiter 11h07m50s +06°38' Leo -1.8 31"9

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