Come on out to watch the Draconids meteor shower. 

(from EarthSky.org)

Unlike many meteor showers, the Draconids are short-lived. In 2022, watch these meteors at nightfall and early evening on October 8. You might catch some on the nights before and after as well. Unfortunately, a full moon on October 9 will hinder this year’s Draconid shower.

(From Wikipedia) A meteor shower is a celestial event in which a number of meteors are observed to radiate, or originate, from one point in the night sky. These meteors are caused by streams of cosmic debris called meteoroids entering Earth's atmosphere at extremely high speeds on parallel trajectories. Most meteors are smaller than a grain of sand, so almost all of them disintegrate and never hit the Earth's surface.

(From EarthSky.org) The radiant point for the Draconid meteor shower almost coincides with the head of the constellation Draco the Dragon in the northern sky. That’s why the Draconids are best viewed from the Northern Hemisphere.

October’s Draconid meteor shower is sometimes called the Giacobinids. This shower produced awesome meteor displays in 1933 and 1946, with thousands of meteors per hour. European observers saw over 600 meteors per hour in 2011.

The Draconids meteor shower’s parent comet, the object responsible for the dust we see burning up in our atmosphere, is the small periodic comet 21P/Giacobini-Zinner. Michel Giacobini visually discovered this comet on December 20, 1900, in the evening sky, from the Nice Observatory in France. The comet was faint and in the southern part of the constellation Aquarius. He was using a 46-centimeter (18-inch diameter lens) refractor telescope, the largest telescope for comet hunting at the time.

This comet comes about as close to the sun as does our earth, then ventures back just past the orbit of Jupiter, before returning 6.6 years later.

This comet was the first visited by a space probe; the International Cometary Explorer visited it in September 1985.

The debris from this comet is not scattered uniformly around its orbit. Much of it is still bunched near the comet. Therefore, when the comet comes back into our neighborhood, it can produce a spectacular meteor shower, known as a meteor storm. This happened in 1933 and 1946, with several thousand meteors an hour. In the years 1985, 1998 and 2018, it produced increased counts but not meteor storms. Jupiter has perturbed the orbit of this comet, with no meteor storms expected.

Enjoy and good hunting!
