Venus and Mercury will share the same right ascension, with Venus passing 5°17' to the south of Mercury.

From Cambridge however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 3° 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 -4.3, and Mercury at mag -0.1, both in the constellation Leo.

The pair will be too widely separated to fit within the field of view of a telescope or pair of binoculars, but will be visible to the naked eye.

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 09h54m50s +08°08' Leo -4.3 49"9
Mercury 09h54m50s +13°26' Leo -0.1 6"1

The coordinates above are given in J2000.0. The pair will be at an angular separation of 25° from the Sun, which is in Cancer 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.
