File:Dione.jpg|DDDD<!-- Dione as seen by [[وویجر ۱]]; the craters prominent at upper and lower left are Dido and Aeneas; to the latter's right are the troughs Latium and Larissa chasmata.EEEE-->
File:Dione limb pano.jpg|DDDD<!-- Panorama with fractures (the Palatine Chasmata) near limb, bisecting craters Euryalus (right) and Nisus just left of center. Crater Silvius is at lower left, with Himella Fossa to its upper right.EEEE-->
File:Dionean Linea PIA08256.jpg|DDDD<!-- Wispy terrain on Dione's trailing hemisphere. The Eurotas (top) and Palatine Chasmata run from upper right to lower left; the Padua Chasmata are near vertical at right, and the Carthage Fossae horizontal at left. The crater Cassandra and its [[ray system]] are at lower right.EEEE-->
File:Dione PIA07748 -Amastrus grooves.jpg|DDDD<!-- Differently sized and oriented fractures within 60-km [[Complex crater|crater]] Amastrus (central peak at lower right). Larger arcuate fractures running from lower left to upper right are the Padua Chasmata, while smaller more parallel fractures from lower right to upper left may be related to the Aurunca Chasmata.EEEE-->
File:Dione PIA07748 -Amastrus grooves inset.jpg|DDDD<!-- Crop of preceding image. The bowl-shaped crater at upper right has bright streaks its walls, and dark material on its floor. To its lower left can be seen an arcuate fracture postdated (covered) by a small crater's ejecta, which in turn is postdated (incised) by parallel fractures.EEEE-->
