The planets Mars and Uranus will make a close approach, passing within a mere 24.1 arcminutes of each other.

From South El Monte , the pair will be visible in the dawn sky, rising at 02:30 (PDT) – 3 hours and 52 minutes before the Sun – and reaching an altitude of 33° above the eastern horizon before fading from view as dawn breaks at around 05:21.

Mars will be at mag 1.5; and Uranus will be at mag 5.6. Both objects will lie in the constellation Gemini.

They will be close enough to fit within the field of view of a telescope, but will also be visible 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 Mars and Uranus around the time of closest approach is available here.

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

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

The circumstances of this event were computed using the DE440 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.
