The planets Venus and Saturn will make a close approach, passing within a mere 39.8 arcminutes of each other.

From South El Monte , the pair will become visible at around 20:42 (PDT), 23° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 2 hours and 31 minutes after the Sun at 22:39.

Venus will be at mag -4.4; and Saturn will be at mag 0.4. Both objects will lie in the constellation Leo.

They will be a little too widely separated to fit comfortably 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 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 09h38m40s 14°42'N Leo -4.4 31"4
Saturn 09h40m00s 15°16'N Leo 0.4 16"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 43° 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.
