Geminids Meteor Shower | 14th December

Normally the Geminids is one of the best meteor showers for the year. Not in 2024! The full moon coincides with the peak of the meteor shower and won’t make it easy to see most of the “shooting stars”. If the Moon wasn’t in its full phase and you were away from artificial light pollution, you might be able to see up to 120 meteors (or “shooting stars”) an hour!

The Geminids meteor shower is generated from asteroid 3200 Phaethon and is one of the most active and best meteor showers to see. Since the asteroid’s discovery on 11th October 1983, by NASA’s Infrared Astronomical Satellite (IRAS), Phaethon has gone around the sun nearly 24 times. Phaethon is 5.1kms across and is one of the largest near-Earth asteroids classified as “potentially hazardous” by NASA. Astronomers have closely monitored this asteroid and there is no high threat level in the foreseeable future.

When and where to look:

The Geminids Meteor Shower is active from 4th to 17th December. The peak of about 120 meteors/hour is from 11pm on 14th December. Viewing is from the north east and north about 45 degrees above the horizon. However, during the Geminids this year, the Moon will be full which will make seeing the fainter meteors hard. You may still see some bright ones though!

What is a meteor shower?

A meteor (commonly called a “shooting star”) is an unexpected, brief streak of light seen in our night sky. It’s caused when space debris, travelling up to 75km per second, enters Earth’s atmosphere. The debris can be as small as a grain of sand which burns up in the atmosphere and causes a bright streak of light to appear briefly in our night sky.

A meteor shower is a celestial spectacle where large numbers of meteors, or “shooting stars”, streak across the night sky. These dazzling events occur when Earth passes through the the trail of debris left by a comet or other object that has come into our Solar System and orbited around the Sun. Visible to the naked eye, meteor showers offer a mesmerizing display of bright streaks, adding a touch of cosmic wonder to the night. 

Where’s the best place to see the meteor shower?

The best place to see a meteor shower is away from bright city lights and when the night sky is dark with no moonlight. Bright moonlight and light pollution makes it harder to see fainter meteors, however you may still be able to see the brighter ones.

Travel out to a dark sky location at one of WA’s Astrotourism Towns. If you’re an astrophotographer, it is an excellent opportunity to image meteors over some of WA’s iconic landscapes. Where are WA’s Astrotourism Towns? 

You don’t need a telescope or binoculars to see a meteor shower. It’s a great time to gather with friends, roll out your favourite picnic rug, pack the drinks and snacks, and start counting how many “shooting stars” you all see! The predicted hourly rate of meteors presumes you’re viewing them in a perfectly dark sky and that the shower is directly overhead. Fingers crossed for a spectacular show!

Something interesting

Meteor showers are named after the constellation where the “shooting stars” appear to be coming from. In the case of the Geminids Meteor Shower, the meteors come from the direction of the constellation of Gemini. If you have a handy smart phone app that helps you identify objects in the night sky, search for the constellation, and you’ll be looking in the right direction.
