The annual celestial event comes as sheer treat for both mature and novice sky-gazers in December 2021.
Geminids are a peculiar meteor shower because it is one of only two that do not arise from a parent comet. Discovered in 1983, Geminid meteor shower is the only one that has an asteroidal parent body called 3200 Phaethon. Like any meteor shower, the Geminids are named after the constellation from which they appear to radiate, in this case the Gemini.
First observed in mid-1800s, Geminids are growing in intensity ever since. While initial observations were around 10-20 meteors per hour, sky-gazers can currently catch around 150 per hour during peak, making it one of the major annual meteor showers.
Geminids are also denser than meteors arising from other showers, which enables them to come as close as 29 miles to Earth’s surface before they burn up.
Best time to watch, what to expect
Geminids are expected to peak on December 14, and the best time window to watch them is between 01:00 am to 04:00 am. For sky-gazers in any part of the world, the peak time to view the Geminids would be around 02:00 am. In a good place, one can easily spot around 50 Geminids per hour.
People watching in the northern hemisphere (includes India) will be able to see more Geminids compared to people in the southern hemisphere.
The moon, a critical factor in visibility of the Geminids, recently entered a new phase. Moonlight can obscure fainter meteors, resulting in sky-watchers only being able to observe fainter ones.
Tips to watch Geminid meteor shower
- Look for a place with fewer trees and city lights.
- The showers will be visible from around 02:00 am and will continue being so after moon sets around 0:300 am till dawn.
- Observe for at least an hour to ensure you see the maximum number of meteors possible
- The Geminids will be visible from the naked eye, so you don’t really need a telescope or a pair of binoculars.
The best way to observe a Geminid is – if you observe a meteor, trace it backwards till your eyes meet the Gemini constellation. If this happens, then it’s a Gemenid meteor.
Live streaming
A live streaming of the Geminids will be done by NASA on its Meteor Watch Facebook page. NASA will broadcast the meteors during the peak with the help of a meteor camera located at the Marshall Space Flight Centre in Alabama.
