Venus and Mars will share the same right ascension, with Venus passing 27' to the north of Mars.
At around the same time, the two objects will also make a close approach, technically called an appulse.
From South El Monte however, the pair will not be observable – they will reach their highest point in the sky during daytime and will be no higher than 7° above the horizon at dusk.
Venus will be at mag -3.9, and Mars at mag 1.8, both in the constellation Cancer.
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 Mars 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 | 09h16m20s | 17°33'N | Cancer | -3.9 | 11"2 |
| Mars | 09h16m20s | 17°05'N | Cancer | 1.8 | 3"7 |
The coordinates above are given in J2000.0. The pair will be at an angular separation of 25° 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.
