The planets Venus and Jupiter will make a close approach, passing within a mere 11.9 arcminutes of each other.

From Fairfield , the pair will be visible in the dawn sky, rising at 04:30 (EST) – 1 hour and 33 minutes before the Sun – and reaching an altitude of 12° above the eastern horizon before fading from view as dawn breaks at around 05:45.

Venus will be at mag -3.9; and Jupiter will be at mag -1.8. Both objects will lie in the constellation Cancer.

They will be close enough to fit within the field of view of a telescope, but will also 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 08h38m20s 19°07'N Cancer -3.9 10"3
Jupiter 08h38m10s 18°56'N Cancer -1.8 30"9

The coordinates above are given in J2000.0. The pair will be at an angular separation of 17° from the Sun, which is in Leo at this time of year.

Warning

Never attempt to point a pair of binoculars or a telescope at an object close to the Sun. Doing so may result in immediate and permanent blindness.

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.
