The biggest meteor shower of the year will peak on Friday 13 December, offering skygazers a rare chance to see hundreds of green shooting stars.
The annual spectacle will deliver up to one meteor every minute on the night of the 12th going into the morning of the 13th, with meteors continuing to appear on a more sporadic basis until 21 December.
The American Meteor Society describes them as the “strongest meteor shower of the year”, though a bright moon may wash out some of the meteors.
The ‘shooting star’ meteors will emanate from the Gemini constellation, which will be relatively well placed in the sky to avoid the worst impacts of the 92 per cent full Moon.
“The constellation of Gemini is well placed from 10pm onward,” the American Meteor Society noted in a blog post detailing the celestial event.
“The Geminids are often bright and intensely coloured. Due to their medium-slow velocity, persistent trains are not usually seen. These meteors are also seen in the southern hemisphere, but only during the middle of the night and at a reduced rate. In 2024, a nearly full moon will greatly reduce the number of meteors seen. If your skies are clear and transparent, you can still see many bright meteors by facing a direction with the moon at your back.”
Nasa has described the Geminids as “gorgeously green” due to the meteors’ chemical composition. The presence of magnesium and nickel means they produce an unusual shade of green when burning up in the Earth’s atmosphere.
“Most meteors appear to be colorless or white, however the Geminids appear with a greenish hue,” said Bill Cooke, lead for the Meteoroid Environment Office at Nasa’s Marshall Space Flight Center in Huntsville, Alabama. “They’re pretty meteors.”
Weather in the UK will not be ideal for the Geminid meteor shower, according to the latest forecast from the Met Office, with clear skies limited to northern parts of Scotland on Thursday evening.
Friday evening will see patchy clouds cover most of the country, offering most people brief moments to see the night sky above.
A less intense meteor shower will take place on 21-22 December, with the Ursids offering a final chance to witness shooting stars in 2024.
