The planets Venus and Saturn will make a close approach, passing within a mere 18.6 arcminutes of each other.

From Columbus , the pair will be difficult to observe as they will appear no higher than 12° above the horizon. They will be visible in the dawn sky, rising at 04:14 (EST) – 1 hour and 47 minutes before the Sun – and reaching an altitude of 12° above the eastern horizon before fading from view as dawn breaks at around 05:28.

Venus will be at mag -3.9; and Saturn will be at mag 0.0. Both objects will lie in the constellation Taurus.

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:

The coordinates above are given in J2000.0. The pair will be at an angular separation of 30° from the Sun, which is in Gemini 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.
