Why it matters

Sudbury expands the Earth catalog and shows the range of confirmed impact structures by scale, age, and preservation state.

What happenedSudbury is a confirmed terrestrial impact structure in a terrestrial setting under editorial verification. This profile records a listed diameter of 130 km and keeps the object ready for editorial expansion.
