Are internet rumours of a comet hurtling towards Earth true?

Rumours across social media platforms that a huge comet is on a collision course with Earth have been circulating, with some users describing it as a major threat to humanity.

Others are debating how the comet – known as 3I/ATLAS and detected by NASA’s ATLAS telescope on July 1 – might be diverted from the Earth. Some have even gone so far as to highlight “news” of military movements and an international coordination to counter the comet before impact, prompting further alarm.

So is there any truth to these rumours and what do we know for sure?

Rumours began spreading after the New York Post published a story on September 29 under the headline: “‘Massive’ comet hurtling toward us is larger than previously thought, could be alien tech, scientist says: ‘It could change everything for us’.”

Users on X (formerly Twitter) circulated screenshots of the article to support their claims. One account, under the name Steven Greenstreet, wrote: “Scientists say a massive alien spaceship is hurtling towards Earth. Why aren’t more people talking about this?”

Another account called Dr Disclosure reposted the story, adding: “This is why all the generals are gathering!” – a reference to a September 30 meeting of US military leaders chaired by Defense Secretary Pete Hegseth. That post racked up more than half a million views.

Meanwhile, an account under the name Richard Roeper shared his concerns: “A massive comet is reportedly hurtling toward Earth at 130,000 mph! Can we stop it? I’m told there are two missions in the works – one involving the specially selected “Messiah Crew,” and one utilizing two squads, known as the Freedom Team and the Independence Team. We got this.”
