Don't get too excited, but Claude Code may have just helped discover a new planet

Published Oct 13, 2026, 12:42 AM EDT Simon is a Computer Science BSc graduate who has been writing about technology since 2014, and using Windows machines since 3.1. After working for an indie game studio and acting as the family's go-to technician for all computer issues, he found his passion for writing and decided to use his skill set to write about all things tech. Since beginning his writing career, he has written for many different publications such as WorldStart, Listverse, and MakeTechEasier. However, after finding his home at MakeUseOf in February 2019, he would eventually move on to its sister site, XDA, to bring the latest and greatest in Windows, Linux, and DIY electronics.

The candidate is ~1.4× Earth, orbits every 3 days; Claude Code ran 74 tests and predicted dimming. TESS has queued observations for November to confirm the dims — so this 'may' become a real discovery. If the past few years taught us that AI has a place within science and technology, then this year has been a lesson on how LLMs have evolved to allow people at home to achieve what used to be exclusively for the experts. For instance, we've already seen a team use AI to generate a suite of open-source Adobe-like products people can download for free. Now, someone has supposedly found a new planet with the help of Claude Code, and while nothing has been confirmed yet, it's really exciting. Claude Code may have just discovered a new planet for NASA Huge emphasis on "may" Credit: Pavel Rabtsevich As spotted by Cybernews, this story begins with Pavel Rabtsevich, a fan of both space and AI. He was taking a look at NASA's data when he spotted a star that dimmed for two hours every three days. Rabtsevich had a hunch that a planet was passing over the star, causing it to dim, so he went through even more data to check if it was consistent. Sure enough, the dimming was still there. So, Rabtsevich got to work. As he explained on X, he began feeding data into Claude Code, OpenAI Codex, and Jev to see if there was a chance that what he saw might be a planet. After pushing the AI to keep thinking and thinking, he eventually deduced that the star was TIC 4206066, and that a potential planet 1.4x bigger than Earth was passing by it every three days, essentially making it a very, very quick year. Rabtsevich then used Claude Code to put his theories to the test, running 74 tests to see if his ideas held up. Sure enough, Claude Code churned through all the data and confirmed that Rabtsevich's theory actually held water. It even correctly predicted when the star's light would dim when Rabsevich hid some data from it and asked it to predict what would happen in the gap. The next step was to actually get this planet confirmed by NASA. To do that, Rabtsevich asked the TESS Project to keep an eye on that specific spot, and they accepted the request. It's now sitting in the queue of TESS tasks to do, and once the telescope passes by that area of space in November, we should get more data on whether the star is actually dimming. Rabsevich already knows what date and time the dims should occur, so all it'd take is for the TESS data to match his own, and he's one step closer to discovering a planet. A few years ago, AI's biggest use was generating funny videos of Will Smith eating spaghetti; today, it's helping people at home discover potential new planets. Who knows where this technology will take us in the future?
