Hot Jupiters

Hot Jupiters are a class of exoplanets that are similar in characteristics to Jupiter but have much higher surface temperatures due to their close proximity to their host stars. These gas giants typically have short orbital periods, often completing a full orbit in just a few days. Their high temperatures are a result of intense stellar radiation, leading to extreme atmospheric conditions. Hot Jupiters are characterized by their large size, significant mass, and unique atmospheric dynamics, which can include strong winds and heat redistribution. They were among the first exoplanets discovered, challenging traditional theories of planetary formation and migration.
