December 2025 promises spectacular sky events for astronomy enthusiasts

December 2025 is shaping up to be an exciting month for stargazers, with a series of remarkable celestial events expected to light up the night sky. So astronomy lovers, buckle up, because there is so much more still left in this calendar year!

Astronomers say interstellar comet 3I/ATLAS will make its closest approach to Earth on December 19, coming within roughly 274 million kilometers. While still a vast distance, the comet’s visit is scientifically significant, as it originates from beyond our solar system. Observers with telescopes of 30 centimeters or larger will be able to catch a glimpse, though experts stress it poses no threat to Earth.

Earlier in the month, on December 7, a rare conjunction of the Moon and Jupiter will occur. During this event, the two celestial bodies will appear unusually close in the sky. If skies are clear, the spectacle will be visible to the naked eye without any telescope.

The year’s Geminid meteor shower will reach its peak on the nights of December 13 and 14, offering a chance to see up to 120 shooting stars per hour. For optimal viewing, experts recommend finding a dark location away from city lights and dressing warmly for the night. Low-intensity lighting and a good vantage point can further enhance the experience.

With multiple highlights across the month, December 2025 is set to be a memorable time for skywatchers and astronomy enthusiasts alike.
