Gázóriás

Gázóriás is the Hungarian term for a gas giant, a type of planet composed primarily of hydrogen and helium. These celestial bodies are characterized by their immense size, significantly larger than terrestrial planets, and their lack of a solid, well-defined surface. Instead, their atmospheres gradually thicken into a fluid interior. Jupiter and Saturn in our solar system are prime examples of gas giants.

The composition of gas giants means they have relatively low densities compared to rocky planets. Their atmospheres are dominated by hydrogen and helium, but they also contain trace amounts of other elements like methane, ammonia, and water, which contribute to the vibrant colors and cloud patterns often observed. The internal structure of a gas giant is thought to consist of a dense, rocky or metallic core, surrounded by a vast ocean of liquid metallic hydrogen, and then enveloped by the gaseous atmosphere.

Gas giants possess powerful magnetic fields and often have extensive ring systems and numerous moons. Their formation is believed to occur in the outer regions of stellar systems, beyond the frost line, where volatile compounds like water, ammonia, and methane can condense into solid ice. These ice particles then accumulate, accreting gas to form the massive planets we recognize as gas giants. Their gravitational influence plays a significant role in shaping the dynamics of their planetary systems.
