Editing Planetary core (section)

====Saturn====
[[Saturn]] has an observed magnetic field generated [[Saturn#Internal structure|within its metallic core]].<ref name="Pollack, et al. 1977"/> Metallic hydrogen is present within the core (in lower abundances than Jupiter).<ref name="Pollack, et al. 1977" />
Saturn has a rock and or ice core 10–30 times the mass of the Earth, and this core is likely soluble in the gas envelope above, and therefore it is primordial in composition. Since the core still exists, the envelope must have originally accreted onto previously existing planetary cores.<ref name="Stevenson 1982" /> Thermal contraction/evolution models support the presence of [[metallic hydrogen]] within the core in large abundances (but still less than Jupiter).<ref name="Pollack, et al. 1977" />
