Halley’s comet gearing up for its return journey toward earth

WORLD  10 December 2023 - 04:03

The futurism.com website says it's been nearly 40 years since Halley's comet last flew by Earth — and very soon, it will be headed back our way. Caliber.Az reprints the article.

As Universe Today reports, this coming Sunday, December 9, the famed comet will reach its furthest point from the Sun. Known as its "aphelion," this is essentially the middle point in Halley's long elliptical orbit through our Solar System.

Named for English astronomer Edmond Halley, who discovered the famed comet and several others in the 18th century, Halley's comet hasn't visible in the night sky since hair metal was all the rage back in 1986.

As exciting as this date is for skywatchers who are waiting for generations to see this gorgeous fireball to streak through Earthly skies — or since 2003, when the European Southern Observatory's Very Large Telescope captured the grainiest of images of the comet as it cruised through the outer edges of our Solar System — they'll still have to wait for quite a while considering that it won't be back around these parts until 2061.

If you're hoping for another telescopic glance of Halley's comet at its furthest, though, you're unfortunately out of luck.

Although both the Hubble and the James Webb space telescopes would certainly be powerful enough to capture images of the comet as it makes its about-face near Jupiter, a NASA spokesperson told Universe Today that there's nothing on either instrument's schedule indicating plans to check it out now or in the future.

While we won't get any glimpses of Halley's comet itself for another few decades, we are able to see remnants of it on Earth in the form of the Eta Aquariids meteor shower.

Every year between late April and early May, our planet passes through debris from the tail of Halley's comet, some of which can leave trails that last for a few seconds or even minutes. While this remnant of the famous fireball is most spectacular in the Southern Hemisphere, those of us up here in the Northern half of the globe aren't completely out of luck — we can see 10 to 20 meteors per hour in the pre-dawn hours of its predicted peak on May 5, 2024.

If you're looking for a skywatching fix before the end of the year, the peak of the Geminids meteor shower is slated for December 13 and 14. In an interview with Space.com, NASA meteor expert Bill Cooke said the viewing conditions for it this year are supposed to be exceptional.
