What is it, when is it and where can I see the Geminid meteor shower this year?

The Geminid meteor shower will peak 13- 14 December

What is the Geminid meteor shower?

The Geminid meteor shower is the last of the year’s major showers, and can generally be relied on to put on a good display. The meteors are very bright, moderately fast, and are unusual in being multi-coloured – mainly white, some yellow and a few green, red and blue. The shower has been known produce over 100 meteors per hour at its peak, although light pollution and other factors mean that in reality, the actual number visible is far less.

Geminids meteors appear to radiate from near the bright star Castor in the constellation Gemini. However, the actual source of the shooting stars is a stream of debris left behind by asteroid 3200 Phaethon, making this one of the only major showers not to originate from a comet.

Meteors are pieces of debris which enter our planet’s atmosphere at speeds of up to 70 kilometres per second, vaporising and causing the streaks of light we call meteors.

How can I watch the Geminid meteor shower?

This year, the peak of the Geminids coincides with a waxing crescent Moon, meaning you will have a good chance of seeing this shower. You can look out for the shower from sunset as the radiant is in the northern hemisphere, although the early hours of 14 December are the expected peak time.

Hunting for meteors, like the rest of astronomy, is a waiting game, so it's best to bring a comfy chair to sit on and to wrap up warm as you could be outside for a while. They can be seen with the naked eye so there's no need for binoculars or a telescope, though you will need to allow your eyes to adjust to the dark. 

Where is best to watch the Geminid meteor shower?

For the best conditions, you want to find a safe location away from street lights and other sources of light pollution. The meteors can be seen in all parts of the sky, so it’s good to be in a wide open space where you can scan the night sky with your eyes. But if you trace the paths that the meteors take, they seem to originate from the Gemini constellation.

Geminid facts

  • Together with the Quadrantids, the Geminids are the only major meteor showers not originating from comet.
  • The beautiful streaks we see in the night sky can actually be caused by particles as small as a grain of sand!
  • Geminids were first observed in 1862, much more recently than other showers such as the Perseids and Leonids.
  • The Geminids are thought to be intensifying every year.
