Respuesta :

Answer:

They counted the craters.

Explanation:

The rate at which impacts have occurred in the Solar System has been roughly constant for several billion years, thus we can estimate the age of the surface of Venus (or any other terrestrial planets in the Solar System) by counting the number of craters.
