Comet Pons-Brooks was the Devil Comet
Comet Pons-Brooks became the Devil Comet in 2024 because of its outbursts that gave it a horned appearance. It made for great photos for astrophotographers.
The comet’s closest approach to the sun (perihelion) was on April 21. At that time it was located in front of the constellation Taurus.
As the comet moved away from the sun, it dropped out of sight from the Northern Hemisphere. But the Southern Hemisphere saw the comet still, heading across the sky toward Orion. It was near Rigel on May 19 and 20.
On June 2, 2024, when the comet was closest to Earth, it was dimmer because it was farther from the sun. On that date, the comet was in front of Lepus the Hare.
Then Comet Pons-Brooks headed back into the outer solar system, where it will remain until it returns in some 71 years.
Comet Pons-Brooks had outbursts
As the comet moved closer to the sun, it underwent periodic outbursts.
The first outburst was on July 20, 2023. It brightened from magnitude 16–17 to magnitude 11–12. Astrophotographers caught the comet outburst, which resulted in a peculiar “horned” appearance, like a devil. It resembled the Millennium Falcon of Star Wars.
The comet continued to have outbursts, including on October 5, November 1 and 14 and December 14 and January 18, 2024. Even as recently as early April, it appeared to be in outburst.

Eliot wrote: “Comet 12P/Pons-Brooks in outburst has resulted in a striking coma. The images are from iTelescopes T24 and T2. The T2, which captured the inset image, shows the green coma. It will be interesting to see how the coma evolves in the next days and whether there will be more outbursts.” Thank you, Eliot!View at EarthSky Community Photos. | David Hoskin in Halifax, Nova Scotia, Canada, captured this image on July 26, 2023. David wrote: “Last night I was able to capture this image of Comet 12P/Pons-Brooks, which recently increased dramatically in brightness as a result of an eruption that produced a debris cloud. The shape of the comet due to the debris cloud is reminiscent of the Millennium Falcon of Star Wars fame.” Thank you, David!View at EarthSky Community Photos. | Filipp Romanov used a remote iTelescope in the Utah desert to capture this image of Comet Pons-Brooks. Filipp wrote: “On July 28 [2023], I observed comet 12P/Pons–Brooks, after its outburst.” Thank you, Filipp!

Comet Pons-Brooks in history
We’ve seen this comet in the past. Jean-Louis Pons and William Robert Brooks both spotted it in the 1800s. The comet now bears the names of those two sky observers.
And even before that, Chinese astronomers observed it as far back as the 1300s.
Comet Pons-Brooks during the eclipse
During the April 8, 2024, total solar eclipse, the comet was near the sun. While it was too dim to see with the eye alone, some astrophotographers caught it in their images.
Not one, but two comets appeared near the Sun during last week's total solar eclipse. The expected comet was Comet 12P/Pons-Brooks, but it was disappointingly dimmer than many had hoped. However, relatively unknown Comet SOHO-5008 also appeared in long duration camera exposures.… pic.twitter.com/P2cG6ikfpK
During the total solar eclipse on April 8, 2024, the sky darkened enough to see Venus and Jupiter. Some astrophotographers caught Comet Pons-Brooks as well. Image via Stellarium/ Kelly Kizer Whitt.

Steven wrote: “Although the comet is only 250 million kilometers (155 million miles) from Earth, with Andromeda 23 trillion kilometers (14 trillion miles) distant, they are now sharing the same part of the sky.” Thank you, Steven!View at EarthSky Community Photos. | Petr Horálek in Revuca, Slovakia, captured Comet Pons-Brooks on March 5, 2024. Petr also captured the Andromeda galaxy along with “a distant tree, the fog illuminated by the passing cars.” Thank you. Petr!

Samit wrote: “During the formation of the solar system, this comet, which is nearly 3 times larger in diameter than Mount Everest, was created with an abundance of ice, rocks and cosmic dust.” Thank you, Samit!View at EarthSky Community Photos. | Eliot Herman in Tucson, Arizona, used a remote telescope in Utah to capture this image of Comet Pons-Brooks on February 25, 2024. Eliot wrote: “Even in bright moonlight, Comet Pons-Brooks is showing well as it continues to brighten. It will perhaps be visible during the April 8, 2024, total solar eclipse.” Thank you, Eliot!View at EarthSky Community Photos. | Petr Horálek in Zdiar, Slovakia, captured Comet Pons-Brooks on March 3, 2024. Petr wrote: “After 3 weeks of cloudy days, I could finally try to catch the brightening comet 12P/Pons-Brooks. Every day more and more beautiful.” Thank you, Petr!View at EarthSky Community Photos. | Greg Redfern was in Albuquerque, New Mexico, when he caught this image of Comet Pons-Brooks, low in the west after sunset. Word had circulated on April 3 that Pons-Brooks is in outburst again, making it brighter than before! And there it is! Will it still be bright tonight? \ No one can say …
Bottom line: Comet Pons-Brooks was the Devil Comet in 2024 thanks to outbursts that gave it a horned appearance. Read more about the comet here.
