Five certain impact craters and 44 additional nearly certain and probable ones have been identified on the 22% of Titan’s surface imaged by Cassini’s high-resolution radar through December 2007. The certain craters have morphologies similar to impact craters on rocky planets, as well as two with radar bright, jagged rims. The less certain craters often

Impact cratering is an important and unique geologic process. The high speeds, forces and temperatures involved are quite unlike conventional endogenic processes, and the environmental consequences can be catastrophic. Kilometre-scale craters are excavated and collapse in minutes, in some cases distributing debris around the globe and exhuming deeply ...

This paper presents a new, global database of lunar impact craters, estimated to be a complete census of all craters with diameters larger than 1–2 km. The database contains over 2 million craters, making it larger in number than any previously published

Abstract The majority of impact craters have circular outlines and axially symmetric morphologies. Deviation from crater circularity is caused by either target heterogeneity, a very oblique impact incidence, post-impact deformation, or by topography.

The Impact Cratering Record on Triton
Science, 1990Impact craters on Triton are scarce owing to the relatively recent resurfacing by icy melts. The most heavily cratered surface has a crater density about the same as the lunar maria. The transition diameter from simple to complex craters occurs at a diameter of about 11 kilometers, and the depth-diameter relationship is ...

Calculations are made to determine the sizes of stony and iron meteoroids which could penetrate the atmosphere of Venus and cause hypervelocity impact craters on the planet's surface. Using scaling relationships based on kinetic energy, impact crater size is related to meteoroid size.

The terrestrial record of meteorite impacts is difficult to decipher because unequivocal evidence of impact is increasingly destroyed with time by erosion, burial, and tectonics.

Polygonal impact craters on mercury
Planetary and Space Science, 2015The existence of polygonal impact craters (PICs) on Mercury is confirmed by this study, which was performed by analyzing 291 named impact craters greater than 12 km in diameter, photographed by the spacecraft Mariner 10 and MESSENGER. All 15 quadrangles of Mercury were scanned for polygonal impact craters with at least two straight rim segments.

IMPACT! - BOLIDES, CRATERS, AND CATASTROPHES
Elements, 2012It is now universally accepted that the impact of planetesimals, asteroids, and comets has been a fundamental process throughout the Solar System. Catastrophic impact events have been instrumental in developing the early history of the planets and have caused environmental disasters throughout Earth history.

Abstract A summary of experimental and theoretical studies of atmosphere-related phenomena accompanying high velocity impact processes is presented, including asteroid and comet passage through the atmosphere, their impact on the surfaces of different planetary bodies, blast waves in the atmosphere and their influence on surface life. These phenomena
