The planets Venus and Jupiter will make a close approach, passing within 2°24' of each other.

From Fairfield , the pair will be visible in the dawn sky, rising at 04:04 (EDT) – 3 hours and 6 minutes before the Sun – and reaching an altitude of 21° above the south-eastern horizon before fading from view as dawn breaks at around 06:52.

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 -4.3; and Jupiter will be at mag -1.9. Both objects will lie in the constellation Ophiuchus.

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 17h00m10s 19°41'S Ophiuchus -4.3 20"8
Jupiter 16h58m40s 22°03'S Ophiuchus -1.9 32"2

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