The author of the article, James Thompson, has "more than a decade of science journalism experience" yet fails to provide sources for his articles, something a high-school student would understand. Another "AI-Generated" article on the "Alabama Gazette" names the planet "Nomad-X." The lack of information leads me to believe it is entirely an AI hallucination and a completely fake story.

Presumably it is about the PSO J318.5-22 (discovered in 2013).

Omitting details makes it more likely to get picked up maybe?

Isn't this big news? I am looking for more information (how far away, closest approach and such).
