Question

Quizplus · Accepted Answer

Hot Jupiters are thought to have migrated inward due to gravitational interactions with the gas disk from which they formed. As they formed, hot Jupiters were likely at a distance similar to Jupiter from our Sun, but the gravitational pull of the gas disk, as well as interactions with other planets and planetesimals, caused them to migrate inward towards their parent star. Gravitational interactions with the gas disk cause the planet to migrate closer to the parent star. As the gas disk dissipates, the planet stabilizes in its new orbit.
