Mercury, the planet orbiting nearest to the sun, is contracting in size, according to WKTV. The station reported the development on Thursday, September 10, 2026, describing the innermost world of our solar system as shrinking.
WKTV framed the finding as one with broader significance, noting that the change raises questions about what it means for the planet and for how researchers view it.
Mercury holds a distinct place in the solar system as the closest planet to the sun. According to WKTV, its gradual reduction in size is the central subject of the reporting, though the station's summary did not lay out the measurements or the mechanism behind the contraction.
The topic has drawn attention beyond a single outlet. WKTV's coverage was surfaced alongside additional headlines and perspectives on the story through Google News, indicating that other news organizations have also picked up the subject.

What drives a planet to shrink, and how quickly the process unfolds, are the kinds of details that determine how significant the finding turns out to be. WKTV's report presents the shrinkage itself as the headline fact, without offering specifics in the summary available.
For readers following the story, the next step is fuller reporting from WKTV and other outlets that explains the observations behind the claim and what they suggest about Mercury's past and future.
