four impact craters — Meteorite crater Four impact craters of the same size (30 km [20 miles] in diameter) imaged by spacecraft on different solid bodies of the solar system and reproduced at the same scale. They are (clockwise from upper left) Golubkhina crater on Venus, Kepler crater on the Moon, an unnamed crater on Jupiter's moon Ganymede, and an unnamed crater on Mars. The images are oriented such that the craters appear illuminated from the left; the Venusian crater is imaged in radar wavelengths, the others in visible light.

The Dalgaranga Crater in Western Australia is identified as an impact crater primarily due to the discovery of both iron and stony meteorite fragments at the site. While the crater has been subject to limited scientific study, its classification as an impact structure is also supported by its specific size and dimensions, measuring 70 feet (21 m) in diameter and 11 feet deep.1
