Mars is made of a solid iron core.
Fat and huge like my butt!
scientist are looking into it, but there is no definite news that there is a core. If there is no core that explains why there is no life on mars and humans can also not live on mars then.
Mars has no rings.
it has the same core as earth, just on another planet
Mars has not been volcanically active for eons as its core cooled long ago since it is only about half the size of earth and radiated its heat faster.
