For questions relating to gas giants: large planets composed of gases (usually mostly hydrogen and helium).
A giant planet is a large planet that is primarily composed of fluid material, rather than rock or other solid matter. There are four giant planets in the Solar System: Jupiter, Saturn, Uranus and Neptune. Many extrasolar giant planets have been identified orbiting other stars.
This tag should be used on questions relating to aspects of these planets: survivability, habitability, and their general dynamics and mechanics.
Be wary that your question is not too physics-based; it's okay to want a scientific answer to a Worldbuilding problem here, but any purely physics question is likely to be closed and migrated. See help/on-topic for more detail.
If you're asking about habitability, there are already some resources on this site that might help you answer your own question:
