A first quarter Moon will make it easy for Northern and Southern Hemisphere observers to view the shower.

Two meteor showers in October

Orionids tend to be active every year in the month of October, usually peaking around October 20. At its peak, people can view about 20 meteors an hour.

The Draconids also occur in October, usually peaking around October 7 - 8.

Halley's comet

The Orionid meteor shower is one of the two meteor showers associated with the Comet Halley. It is called Orionids because the meteors seem to emerge or radiate from the constellation Orion.

The Eta Aquarids in May is the second meteor shower created by the debris left by Comet Halley. Halley takes around 76 years to make a complete revolution around the Sun. It will next be visible from Earth in 2061.

Where to view the Orionids

The Orionids can be seen by viewers from both hemispheres.

While it is not necessary to look in a particular direction to enjoy a meteor shower – just lay down on the ground and look directly above and you are bound to see some meteors – astronomers suggest that observers in the Northern Hemisphere look towards the southeastern sky, while those in the Southern Hemisphere look at the northeastern sky.

When to view the Orionids

The best time to view the Orionids is just after midnight and right before dusk.

How to view the Orionids

There isn’t a lot of skill involved in watching a meteor shower. Here are some tips on how to maximize your time looking for the Orionids:

  • Get out of the city to a place where city and artificial lights do not impede your viewing
  • If you are out viewing the shower during its peak, you will not need any special equipment. You should be able to see the shower with your naked eyes.
  • Carry a blanket or a comfortable chair with you - viewing meteors, just like any other kind of star gazing is a waiting game, and you need to be comfortable. Plus, you may not want to leave until you can’t see the majestic celestial fireworks anymore.
  • Check the weather and moonrise and moonset timings for your location before you leave, and plan your viewing around it.
