Venus and Mercury will share the same right ascension, with Venus passing 25' to the north of Mercury.

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 1° above the horizon at dusk.

Begin typing the name of a town near to you, and then select the town from the list of options which appear below.

Venus will be at mag -3.9, and Mercury at mag 2.3, both in the constellation Taurus.

The pair will be close enough to fit within the field of view of a telescope, but will also be visible 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 two objects at the moment of conjunction will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
Venus 05h35m30s 24°06'N Taurus -3.9 10"2
Mercury 05h35m30s 23°41'N Taurus 2.3 10"6

The coordinates above are given in J2000.0. The pair will be at an angular separation of 16° from the Sun, which is in Taurus 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.
