Approximately how long ago did the impact that formed the Tycho crater occur in geological terms?
Answer
100 to 110 million years ago
The impact event that created the massive scar known as Tycho is considered geologically recent, with estimates placing its occurrence between 100 and 110 million years ago. This relatively young age is the primary reason why Tycho remains one of the best-preserved large craters visible on the lunar near side. Its youth means that its sharp features, such as terraced walls and the distinct central peak, have not yet been significantly degraded by the cumulative erosion caused by billions of years of micrometeorite bombardment, unlike much older features on the Moon.
