Mars has a molten core whose radius has been estimated at between 1810 and 1860 kilometers, about half that of Earth!
NASA’s InSight probe has already recorded more than 500 earthquakes, of which more than fifty between magnitude 2 and magnitude 4.
Thanks to these earthquakes it was possible to study for the first time the interior of the planet and thus reach the incredible discovery of the presence of a nucleus “melted” much larger than expected.
Earthquakes, large molten core and large amounts of water trapped in the crust, does this seem the image of a dead planet?
