The mantle is a layer inside a terrestrial planet and some other rocky planetary bodies. For a mantle to form, the planetary body must be large enough to have undergone the process of planetary differentiation by density. The mantle lies between the core below and the crust above. The terrestrial planets (Earth, Venus, Mars and Mercury), Earth's Moon, two of Jupiter's moons (Io and Europa) and the asteroid Vesta each have a mantle made of silicate rock.<ref name="EarthMantle">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="VenusMantle">{{#invoke:Citation/CS1|citation |CitationClass=journal }}</ref><ref name="MarsMantle"></ref><ref name="MercuryMantle">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="TheMoonMantle">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="Io">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="EuropaMantle">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="VestaMantle">{{#invoke:Citation/CS1|citation |CitationClass=journal }}</ref> Interpretation of spacecraft data suggests that at least two other moons of Jupiter (Ganymede and Callisto), as well as Titan and Triton each have a mantle made of ice or other solid volatile substances.<ref name="GanymedeMantle">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="CallistoMantle">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="TitanMantle">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref><ref name="TritonMantle">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
