Halley’s Comet (a celestial body made of dust, ice, and rock that orbits the sun) is a short-period comet that is consistently visible to the naked eye from Earth, appearing every 72–80 years. The Orionids meteor shower is finally taking place from September 26 to November 22, 2024. This magnificent event is especially fascinating as it is associated with the immensely popular Halley’s Comet, turning it into a notable highlight for both hobbyists and experienced astronomers.
Important viewing dates
The apex of the Orionids is predicted to be apparent throughout the night on October 20-21, 2024. Although meteors can be seen during the whole duration of the shower, the most favourable conditions will be during this peak period.
Meteor activity expectations
At its peak, the Orionids normally bring about 20 meteors per hour. Even so, under favourable conditions, this number can climb dramatically, reaching 50 to 75 meteors per hour in specific timeframes. This year, the perceptibility is believed to be reduced due to a waning gibbous moon that will rise before midnight, possibly obscuring low-intensity meteors. To enhance your likelihood of getting a better glimpse, try looking as soon as it gets dark.
The connection to Halley’s comet
The Orionids are known to originate from debris emitted by Halley’s Comet, which previously passed by Earth in 1986 and is next predicted to return in 2061. Identified by Edmond Halley in the 17th century, this comet has a 76-year orbital cycle, declaring it one of the most recognizable comets. As Earth goes across the dust cloud and particles left by Halley’s Comet, the aforementioned small fragments burst into flames upon entering our atmosphere, forming breathtaking meteor displays.
Halley’s impact on other meteor showers
Halley’s Comet is the root of two significant meteor showers each year- – the Orionids in October and the Eta Aquarids in May. These meteor showers manifest as the Earth moves across different sections of the debris trail of the comet.
Tips for a breathtaking viewing experience
To have a magnificent viewing experience of the Orionids, here is a carefully curated list of the following suggestions you should keep in mind, based on the data provided by NASA.
Look for open spaces
Try choosing spots with a clear and discreet view of the sky, steering clear of any tall trees or buildings.
Seek dark areas
Focus on finding locations far from city lights, such as International Dark Sky Parks or even rural areas, considering the minimal pollution of light.
Timing matters
Late nights, particularly after midnight, are perfect for getting a good glimpse of meteors. Make time to watch for a minimum of at least 30 minutes, allowing your eyes to adjust to the darkness.
Skip the telescopes
Using telescopes or binoculars may limit your vision, making it challenging to watch the fast-moving meteors. The best view is often with the naked eye.
