Don’t miss the Orionid meteor shower this weekend; Halley’s comet shedding dust particles as it orbits the sun is what brings about this annual celestial event.

Although the Orionids are not the most spectacular of sky shows, meteor enthusiasts look forward to the cosmic event for its consistency in timing and intensity.

“They are pretty much an Old Faithful type of reliable shower,” said Alan MacRobert, a senior editor at Sky and Telescope magazine.

The shower should peak during the early morning hours of October 21 but will be visible from October 20 to 24.

The who are curious to see the show might want to brew some coffee. The Orionids are best spotted in the hours between moonset—typically well after midnight—and the start of dawn some 90 minutes before sunrise.
