October is the peak time to view this astronomical event.
2025 has been a dazzling year of astronomical events. The planetary parade alongside a host of meteor showers like the Perseid has delighted stargazers, perfectly in line with the growing astrotourism trend. The astronomical events are set to continue this year, with the Orionid meteor shower set to peak later this month.
October 2025 is set to be a particularly good year for viewing the Orionid meteor shower, as it lines up with a new moon, which means darker skies and therefore better visibility from Earth.
What are comets and meteor showers?
World-renowned astrophotographer and educator Adam Block from the Steward Observatory, part of the Department of Astronomy at the University of Arizona, explains that comets are remnants from the early part of the solar system, made from both water ice and other frozen gases.
“Basically, you have a ball of rock with a trail of gas coming out behind it. It’s the sun that controls all of that; the solar wind blows the gas back," he tells Australian Traveller. “But it’s not just gas; there are also particles of dust released and liberated from the surface of this dirty iceball."
That gas and dust particles released from the surface form a tail behind the comet, creating a trail in space.
“If the Earth runs through that stream of dust, those dust particles will enter the Earth’s atmosphere at around 30 kilometres per second, so they literally burn up in the upper atmosphere," he says.
Simply put, the resulting light trail is the meteor.
The Orionids and Halley’s comet
Halley’s Comet is one of the most famous comets. Last seen in 1986, it appears roughly every 75 years, with its expected return in 2061. Even though Halley’s Comet isn’t visible in the sky right now, the Orionids are one of the two meteor showers that it creates.
When is the best time to see the Orionids?
The Orionids meteor shower occurs from 26 September to November.
According to Adam, the best time to view the Orionids is after midnight, when the Earth is turned and facing the same direction as we are travelling through space, and it directly encounters the meteoroid stream.
October 20-21 will offer the best viewing opportunities because of the new moon, which offers extra dark skies. Adam also advises heading away from city lights.
How to see the Orionid meteor shower
The good news, according to Adam, is that you don’t need a telescope or optical aid to witness the event; you just need “a dark sky, a clear view and some patience."
For the Orionids, the average is roughly 20 meteors per hour. But given you can’t see the whole sky at once, Adam says you’re doing well if you see a meteor once every five or 10 minutes.
And if you’re lucky, he says you might even see a fireball, also known as a bolide.
