Conjunction of Venus and Mercury

Venus and Mercury will share the same right ascension, with Venus passing 19' to the south of Mercury.

At around the same time, the two objects will also make a close approach, technically called an appulse.

From South El Monte , the pair will become visible at around 20:24 (PDT), 12° above your western horizon, as dusk fades to darkness. They will then sink towards the horizon, setting 1 hour and 33 minutes after the Sun at 21:34.

Venus will be at mag -4.2, and Mercury at mag -0.5, both in the constellation Gemini.

The pair 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.

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 06h07m00s 25°16'N Gemini -4.2 52"7
Mercury 06h07m00s 25°36'N Gemini -0.5 6"3

The coordinates above are given in J2000.0. The pair will be at an angular separation of 20° from the Sun, which is in Taurus at this time of year.
