Vivaldi (crater)

Vivaldi is a crater on Mercury. It was named by the IAU after Italian composer Antonio Vivaldi in 1976.^[1] It has a prominent and nearly continuous inner ring whose diameter measures about half that of the outer ring. It is one of 110 peak ring basins on Mercury.^[2] Unlike some of the lunar multiringed structures, no vestiges of additional rings are apparent around this crater. It is classified as c3 age.^[3]
