The Orionid meteor shower will peak this weekend as Earth bursts through a field of dust and debris left in the inner solar system by Halley's comet.

Although the Orionids are active from Sept. 26 through Nov. 22, the best time to watch will be in the early hours of Saturday, Oct. 21, when around 23 "shooting stars" are expected per hour, according to the American Meteor Society. The precise peak is at 1 a.m. EDT (0500 GMT), with shooting stars from this medium-intensity shower striking Earth's atmosphere at a swift 41 miles per second (66 kilometers per second), or around 148,000 mph (238,000 km/h).

Now beyond Neptune, Halley's comet orbits the sun roughly every 76 years, making it the only known naked-eye comet that can theoretically be seen twice in one human lifetime. Next, it will loop around the sun, passing close to Earth in 2061. This November and December, the giant comet will reach aphelion, its farthest point from the sun, before it begins its return trip to the inner solar system, according to EarthSky.
