The planet Venus and Jupiter's moon Europa have numerous lineae; Saturn's moon Rhea and the dwarf planet Pluto have several.{{Cite encyclopedia |title=Europa |encyclopedia=Encyclopedia of Astrobiology |publisher=Springer |location=Berlin |url=https://books.google.com/books?id=oEq1y9GIcr0C&pg=PA512 |last=Encrenaz |first=Therese |date=2011 |editor-last=Gargaud |editor-first=Muriel |series=Springer Reference |volume=1 |page=512 |isbn=978-3-642-11271-3 |oclc=537271559 |quote=The most striking features of Europa's surface are the series of dark streaks, called “lineae” that crisscross the whole globe |editor2-last=Amils |editor2-first=Ricardo |editor3-first=Henderson James |editor-last3=Cleaves |display-editors=1}} {{Cite book |last=Hall III |first=James A. |title=Moons of the Solar System: from Giant Ganymede to Dainty Dactyl |date=2015 |publisher=Springer |isbn=978-3-319-20636-3 |series=Astronomers' Universe |location=Cham Heidelberg |page=[https://books.google.com/books?id=HgmVCgAAQBAJ&pg=PA93 93] |bibcode=2016mss..book.....H |doi=10.1007/978-3-319-20636-3|quote=Lineae: The lineae are lines that cross the surface}}

On Mars, recurring slope lineae form seasonally on warm Martian slopes as dark downhill streaks, growing during warm seasons and fading in cold seasons. They are thought to be either caused by salty liquid water flows during warm months, or dry grains flowing down in a kind of landslide.
