The planets Venus and Saturn will make a close approach, passing within a mere 8.8 arcminutes of each other.

From Fairfield , the pair will be visible in the dawn sky, rising at 03:40 (EDT) – 3 hours and 32 minutes before the Sun – and reaching an altitude of 26° above the south-eastern horizon before fading from view as dawn breaks at around 06:35.

Venus will be at mag -4.2; and Saturn will be at mag 0.5. Both objects will lie in the constellation Libra.

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 Saturn 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 14h44m30s 13°25'S Libra -4.2 16"6
Saturn 14h44m10s 13°33'S Libra 0.5 15"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 42° from the Sun, which is in Ophiuchus 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.
