In an article on Venus by JPL from 1996 I read

Due to the dense Venusian atmosphere, primary impact craters of less than a 3 kilometer (2 mile) diameter are nonexistent.

I am now wondering whether there is somewhere a comprehensive list of (other) directly observed strikes of incoming rocks on Venus e.g. by atmospheric anomalities?

Side-question: What minimal size must an object entering Venus' have in order to reach the ground and/or leave an obserable trace on the surface?

  • $\begingroup$ @NilayGhosh From your comment I conclude: The numbers of craters is only an upper bound for the number of incoming objects on planets with a dense atmosphere as the latter breaks up meteors which potentially form multiple overlapping craters. $\endgroup$
