This slide allows for a comparison of ~30-kilometer-diameter impact craters on several planetary bodies. All craters are shown at the same scale and have been rotated so that the light source is from the left. This rotation makes north at the bottom of the images of the lunar crater and the Ganymede crater. Names and locations of the four craters are as follows: Venus (Golubkhina), 60.3°N, 286.4°E; Moon (Kepler), 8.1°N, 38.1°W; Mars, 20.8°S, 53.6°E; Ganymede, 29.8°S, 136.0°W.
Image of Ganymede crater contributed by Paul Schenk (Lunar and Planetary Institute). Image of Mars crater obtained from the Mars Multi-Scale Map, Calvin Hamilton (Los Alamos National Laboratory).
