German Aerospace Center researchers said Mercury is losing about 14 miles of its radius, roughly 30 % faster than earlier estimates. Earlier analysis of MESSENGER data had suggested a possible radius reduction of up to 11. 6 km, and subsequent studies indicated the planet’s diameter could have shrunk by as much as 14.

5 miles since its formation; the BepiColombo mission is slated to investigate the finding. The latest report follows earlier publications that highlighted the larger-than-expected contraction and noted that BepiColombo’s measurements will be used to verify the new estimates.
