There probably more habitable planets outside of the habitable zone. Retaining an atmosphere depends on the size of the planet. The core is ade up of h compounds, rock and metals. The (cid:272)o(cid:396)e is(cid:374)"t a solid, it"s a plas(cid:373)a. It (cid:373)ight (cid:271)e solid at the (cid:272)o(cid:396)e, (cid:271)ut its (cid:374)ot solid above the core. Each band corresponds to a slightly different height in the atmosphere. These winds and complex turbulence make it unlikely for there to be life on jupiter. In the inner solar system, theres our moon and mars has 2 satellites. Theres 180 and we are still finding more. Theres more than 100 moons just around jupiter. Theres different numbers of moons because sometimes they are behind the planet. Io is the densest of them all because of the solar nebula theory where it formed in the hottest region.
