The planets Venus and Mercury will make a close approach, passing within a mere 20.3 arcminutes of each other.

From South El Monte , the pair will be difficult to observe as they will appear no higher than 9° above the horizon. They will be visible in the dawn sky, rising at 05:31 (PDT) – 1 hour and 7 minutes before the Sun – and reaching an altitude of 9° above the eastern horizon before fading from view as dawn breaks at around 06:23.

Venus will be at mag -3.9; and Mercury will be at mag -1.1. Both objects will lie in the constellation Leo.

They 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.

At around the same time, the pair will also share the same right ascension – called a conjunction.

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 10h54m10s 8°26'N Leo -3.9 10"1
Mercury 10h54m40s 8°45'N Leo -1.1 5"7

The coordinates above are given in J2000.0. The pair will be at an angular separation of 14° from the Sun, which is in Virgo 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.
