This weekend offers an extraordinary celestial spectacle as the "Cold Moon," the year's final and longest full moon, illuminates the night sky on December 15. This rare event, steeped in both natural beauty and cultural significance, will not recur until 2043.

Why is it called the Cold Moon?

The Cold Moon gets its name from December's long, frigid nights. Native American tribes historically referred to it as the "Long Nights Moon" or the "Moon before Yule," reflecting its proximity to the winter solstice on December 21.

The Cold Moon will reach its peak illumination at 4:02 a.m. ET (2:32 p.m. IST). Weather permitting, it will remain visible for hours before and after this time.

Unique features of 2024 Cold Moon

This year’s Cold Moon coincides with the "major lunar standstill," a phenomenon occurring once every 18.6 years. During this event, the moon's orbit reaches its most extreme northern and southern positions, creating the moon's farthest northern rise and set points of 2024.

This spectacular alignment is due to Earth’s axial tilt and the moon’s wobbling orbit. After this weekend, the moon will not reach such northern extremes until 2043.

Cold Moon and the Geminid meteor shower

The Cold Moon’s brilliance may overshadow the Geminid meteor shower, peaking on Friday night. Known as one of the most reliable meteor showers, the Geminids will still be visible on Saturday night, but the moon's radiant glow might make spotting meteors challenging.
