===Surface features=== A study by Hanus et al. using data from the [[Very Large Telescope|VLT]]'s SPHERE instrument names eight craters 20 to 40 km in diameter, and seven recurring features of unknown nature that remain nameless due to a lack of consistency and their occurrence on the edge of Iris. The names are Greek names of colors, corresponding to the rainbow as the sign of Iris. It is unknown whether these names are under consideration by the [[IAU]]. The other 7 features are labeled A through G.<ref name="Hanus2019"/> {| class="wikitable" |+ Named craters on Iris |- ! width=100 | Feature !! Pronunciation !! Greek !!
