Invite you to observe the year-end astronomical event, the Geminids meteor shower, on the night of 14 to early morning 15 December 2025, visible throughout all regions of Thailand.
On 12 December 2025, a report stated that the fan pageNARIT, the National Astronomical Research Institute of Thailand,posted that on 14 to early 15 December 2025, the Geminids meteor shower will reach a peak rate of about 150 meteors per hour. The radiant point of the meteor shower is located in the Gemini constellation. Viewers can start watching from around 8:00 PM when Gemini rises in the eastern horizon, continuing until 2:30 AM, after which moonlight interference increases.
Additionally, the night of 13 to early 14 December also offers a chance to see the Geminids meteor shower, though moonlight will begin to interfere from about 1:40 AM. The night of 14 to early 15 December is expected to have the highest meteor rate.
Those interested in watching the meteor shower can choose a convenient time and should seek out open, completely dark areas away from city lights, such as mountain clearings, hilltops, plains, or reservoirs. If skies are clear and cloudless, the meteor shower can be seen from all regions across Thailand. It is recommended to lie down and scan the sky in all directions to catch the meteors.
The Geminids meteor shower, associated with the Gemini constellation, occurs annually between 4 and 20 December. It happens as Earth passes through a stream of debris, including rocks and dust, left behind by the asteroid 3200 Phaethon when it moves through the inner solar system.
As Earth orbits through this debris trail, its gravity pulls these rocks and dust particles into the atmosphere, causing friction and burning that appears as bright streaks or fireballs moving across the sky. Unlike ordinary shooting stars, meteor showers have a radiant point—a specific spot in the sky from which meteors appear to originate. When this radiant is near a constellation, the meteor shower is named after that constellation.
