Close approach of Mars and Jupiter

• The two celestial objects appear near one another from our viewpoint on Earth, offering an interesting sight for observers with a clear sky.

• The closest approach occurs during the daytime in the UK, so look for the pairing when the objects are above the horizon and the sky is dark enough to observe them.

• Also this month ~ the Moon makes another close approach to Mars on Monday 30th November 2026.
  o

• Captured two planets coming out to view through the morning mist at 6am by smartphone – looking up, I can still see Jupiter making a close approach to Mars.
  o
