WebJun 11, 2016 · So, gas giants may have rocky cores. They may have no cores as such at all. Their centres being metallic hydrogen or ices under high pressures. We need to take highly precise gravitational measurements of Jupiter to determine this. Answer link WebGas giants may have a rocky or metallic core but the majority of their mass is in the form of gas (or gas compressed into a liquid state – to get an idea of what this could be like, …
If gas giants have a rocky core, are they essentially just rocky ...
WebJul 1, 2024 · Giant planets like Jupiter and Saturn have a solid planetary core beneath a thick envelope of hydrogen and helium gas. But no-one … Dynamo theory is a proposed mechanism to explain how celestial bodies like the Earth generate magnetic fields. The presence or lack of a magnetic field can help constrain the dynamics of a planetary core. Refer to Earth's magnetic field for further details. A dynamo requires a source of thermal and/or compositional buoyancy as a driving force. Thermal buoyancy from a cooling core alone cannot drive the necessary convection as indicated by modelling, thus compositional buo… edwin j. bowman lincs

WebMar 21, 2024 · A gas giant is a large planet composed mainly of gases, such as hydrogen and helium, with a relatively small rocky core. One of Neptune’s moons, Triton, orbits the planet in the opposite direction that Neptune rotates, implying that Triton was captured, perhaps by Neptune’s once larger atmosphere, in its wake. WebWith the outer planets, when you read about a "rocky" core, you should just think "a core with lots of the elements that rocks are made of on Earth," not a solid surface that some super-strong machine could roll around on. In fact, the terms "gas giant" and "ice giant" can both be a little misleading. WebNov 9, 2024 · In a new study based on this mechanism, DTM astrophysicist John Chambers found that gas giants in early stages of formation may have had oceans with steaming atmospheres before growing into gas … contact bt support by phone
