Orionid Meteor Shower Peaks this Weekend!

Starry Night by Steven Karsten

The annual Orionid shower peaks this Saturday, but Earthsky’s page on the Orionid Meteor shower says that Friday night might be the best viewing:

The Orionid meteor shower is expected to peak this weekend, though this year, in 2018, the shower must compete with the glare of the brilliant waxing gibbous moon for much of the night. As is standard for many meteor showers, this shower takes place primarily between midnight and dawn – regardless of your time zone. Typically, the Orionids’ strongest showing comes during the few hours before dawn. offering perhaps 10 to 15 meteors per hour in a dark sky.

The advantage of watching late Friday to Saturday morning – rather than the following nights – is that there is less moonlight to obstruct the show.

The Orionids stem from bits and pieces from the most famous of all comets, Comet Halley, pictured above. The picture shows Comet Halley itself at its 1910 visit. The comet last visited Earth in 1986 and will return next in 2061.

As Comet Halley moves through space, it leaves debris in its wake that strikes Earth’s atmosphere most fully around October 20-22, every year. The comet is nowhere near, but, around this time every year, Earth is intersecting the comet’s orbit.

If the meteors originate from Comet Halley, why are they called the Orionids? The answer is that meteors in annual showers are named for the point in our sky from which they appear to radiate. The radiant point for the Orionids is in the direction of the constellation Orion the Hunter. Hence the name.
