Ruwa da kankara, bisa ga astrophysicists, a manyan lambobin samu a cikin subsoil - wani siffa da cewa characterizes Ganymede. The most na amaryar wata na Jupiter yana da uku ciki yadudduka:

• zubi core, kunsha ko dai kawai na karfe ko karfe da kuma sulfur impurities.

• alkyabbar kunshi dutse.

Zai yiwu tsakanin kankara da alkyabbar ne a Layer na ruwa ruwa. A wannan yanayin yana da zazzabi kasa sifili, amma ba ya daskare saboda da babban matsin. A Layer kauri aka kiyasta ya zama 'yan kilomita, shi ya ta'allaka ne a zurfin 170 km.

Magnetic filin

Ganymede tauraron dan adam ne ba kawai Duniya-kamar tectonics. Wani sananne alama ne da iko Magnetic filin ne daidai da wannan samuwar wannan duniya tamu. Masana kimiyya bayar da shawarar cewa wannan sabon abu a cikin hali na Ganymede iya zama dalilai biyu kawai. A farko - zubi core.
