Calling all Sydney stargazers: the biggest meteor shower of the year will be lighting up the sky on the night of Saturday, December 14 and the morning of Saturday, December 15, with 150 meteors shooting above us when the meteor shower is at its peak. The Geminids meteor shower is one of the final celestial spectacles for the year and it's one worth seeing. Sydney is home to some pretty spectacular stargazing spots, but if you want to get the most out of the Geminids – get to the Blue Mountains to watch it with an astronomer by your side.
While most meteor showers are the result of a comet, the Geminids come from debris shed by 3,200 Phaethon, a five-kilometre-wide asteroid that discards matter as it moves past Earth in space. It first appeared in the mid-1800s, but it wasn't considered particularly notable at the time, offering just ten to 20 meteors per hour at its peak. The Geminids have grown considerably in scale across the centuries, today offering upwards of 120 meteors per hour in perfect conditions. This particular starry display is considered one of the best and most reliable annual meteor showers, according to NASA.
This year, the Geminids will be visible in Sydney from around December 4 until December 20, with a peak set to occur on the night of December 14 to the morning of December 15. The visibility of the meteors can vary based on moonlight and weather, and since the moon will be relatively bright on the weekend of December 14, we’re not looking at prime conditions this time around. According to the good people from Blue Mountains Stargazing, we should still be able to see around 50 stars per hour – in our opinion, that’s still worth getting out of bed for.
