eponym=Yuty ,Paraguay Yuty Crater is a crater in
Chryse Planitia , on the planetMars .The crater is about 18km in diameter, and is surrounded by complex
ejecta lobes, one of which partly covers an older crater.cite web|url=http://nssdc.gsfc.nasa.gov/imgcat/html/object_page/vo1_003a07.html|title=Yuty crater in Chryse Planitia, Mars|work=Mars - Viking 1 Orbiter|year=1976|accessdate=2007-05-14] Many craters at equatorial and mid-latitudes on Mars have this form of ejecta morphology, which is believed to arise when the impacting object melts ice in the subsurface. Liquid water in the ejected material would then allow it to flow, forming the characteristic lobe shapes.cite web|url=http://sse.jpl.nasa.gov/scitech/display.cfm?ST_ID=25|title=Maximum Impact - Impact Craters in the Solar System|work=NASA Solar System Exploration|author=Walter S.
