There are two common definitions in use for the surface of gas planets: The 1-bar surface: As pressure increases, the deeper in we go into the gas planet, we will hit a pressure of 1 bar at some altitude. Gas at this altitudes will usually sit deep enough in the gravitational well and be of a near-uniform density and temperature, as ... WebThe assumption based on our models of how giant planets form is that they do have solid cores made of rock and ice. Our best models suggest that giant planets form through core accretion. Just about at the distance of Jupiter, we find the "snow line", where sunlight is just weak enough that exposed water is stable as ice. Presumably as the Sun ...

Do Gas Giants Have A Solid Core?(Answered!) - Scope The Galaxy

WebMar 6, 2024 · A gas giant planet is large enough that it retains a lot of hydrogen and helium. A rocky planet is one with a solid surface. That's the rule of thumb to distinguish between the rocky and gaseous planets. But gaseous planets can have a solid core and rocky planets can have a very thick atmosphere. WebGas, no.
