The latest consensus is that the asteroid was roughly 10–15 kilometers (6–9 miles) in diameter, with a Chicxulub-scale impact crater about 180 kilometers (112 miles) across . Estimates over the past few years have generally converged around this size range, though exact dimensions depend on the specifics of the impact and crater reconstruction .[7]

If you’d like, I can pull the most recent primary sources or summarize how the size estimates are inferred from crater dimensions, iridium layers, and crater imaging. I can also provide a short, cited reading list in Prague-friendly access.
