The planets Saturn, Mars and Uranus will make a close approach, passing within a mere 55.9 arcminutes of each other.

From South El Monte , the trio will be visible in the dawn sky, rising at 02:31 (PDT) – 3 hours and 51 minutes before the Sun – and reaching an altitude of 37° above the eastern horizon before fading from view as dawn breaks at around 05:41.

Saturn will be at mag 0.1; Mars will be at mag 1.5; and Uranus will be at mag 5.6. The trio will lie in the constellation Gemini.

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

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

A graph of the angular separation between Saturn and Mars around the time of closest approach is available here.

The positions of the trio at the moment of closest approach will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
Saturn 07h55m30s 20°44'N Gemini 0.1 17"1
Mars 07h56m10s 21°39'N Gemini 1.5 4"5
Uranus 07h56m00s 21°15'N Gemini 5.6 3"6

The coordinates above are given in J2000.0. The trio will be at an angular separation of 48° from the Sun, which is in Leo at this time of year.
