Copernicus (lunar crater) the side of the crater midpoint that is closest to Copernicus. Copernicus H, a typical "dark-halo" crater, was a target of observation by Lunar Orbiter 5 in 1967. Dark-halo craters were once believed to be volcanic in origin rather than the result of impacts. The Orbiter image showed that the crater had blocks of ejecta like other craters of similar size, indicating an impact origin. The halo results from excavation of darker material (mare basalt) at depth. Copernicus (lunar crater) Copernicus is a lunar impact crater named after the astronomer Nicolaus Copernicus, located in eastern Oceanus Procellarum. It typifies craters
