The most prolific meteor bathe of the yr, the Geminids, will peak in a single day on Friday and Saturday (Dec. 13 and 14). The solely annual meteor bathe that scientists know for certain is attributable to an asteroid slightly than a comet, the Geminids meteor bathe’s peak night time will this yr be considerably dampened by the looks of a near-full moon.
With December’s full moon, the “Cold Moon,” rising on Sunday, Dec. 15, it should already be above the horizon and shining brightly because the solar units on Dec. 13. Skywatchers are unlikely to see as lots of the (as much as) 120 taking pictures stars per hour in the course of the peak that many hope for — however that is nonetheless an occasion to be exterior for round midnight.
For the very best view, discover a spot as removed from synthetic lights as attainable, flip your again to the moon, and search for whereas permitting your eyes to regulate to the darkness. Meteor showers are finest considered with the bare eye; no skywatching binoculars or yard telescopes needed. (Due to the moon’s vibrant glow, in depth journey for this bathe just isn’t suggested.)
The strongest meteor bathe of the yr within the Northern Hemisphere, the Geminids are sometimes vibrant and intensely coloured, in accordance with the American Meteor Society. Active from Monday, Dec. 2 to Saturday, Dec. 21, the Geminids are usually yellow, in accordance with NASA, however may additionally be white and inexperienced.

The Geminids are attributable to 3200 Phaethon, which is considered an asteroid. Each December, Earth crosses the asteroid’s path; particles left within the wake of the asteroid tumbles by means of Earth’s environment, heating up and producing “taking pictures stars,” or meteors. Discovered in 1982, asteroid Phaethon orbits the solar each 1.4 Earth years and shows a comet-like tail for just a few days when the asteroid passes closest to the solar. That’s uncommon; asteroids, that are principally rocky, don’t usually kind tails after they get near the solar.
Research printed in 2023 revealed that sodium fuel is launched from the minerals in 3200 Phaethon whereas carbon dioxide and water vapor trigger sufficient stress to raise small mud particles from its floor. Together, these two processes kind its tail.
As the Geminids peak this yr, 2024’s remaining meteor bathe may even be getting underway. The Ursids, which seem to return from Ursa Major — most well-known for its form of stars referred to as the Big Dipper — runs from Friday, Dec. 13 by means of Tuesday, Dec. 24, peaking in a single day on Saturday, Dec. 21 and Sunday, Dec. 22, when 5-10 taking pictures stars could also be seen in darker night time skies. On that peak night time, the yr’s final quarter moon will rise after midnight.
