The planets Venus and Mercury will make a close approach, passing within 1°21' of each other.

From Columbus however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 5° above the horizon at dawn.

Venus will be at mag -3.9 in Aries; and Mercury will be at mag -0.1 in Cetus.

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.

A graph of the angular separation between Venus and Mercury 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 02h04m10s 10°54'N Aries -3.9 10"9
Mercury 02h07m10s 9°47'N Cetus -0.1 6"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 24° from the Sun, which is in Taurus 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.
