What defines a Hot Jupiter's orbital period compared to Solar System Jupiter?
Answer
Orbiting in less than ten days or even hours
The primary defining characteristic that sets a Hot Jupiter apart from the Jupiter found in our own Solar System is its incredibly tight orbit around its host star. Solar System Jupiter requires nearly twelve Earth years to complete one revolution. In stark contrast, a Hot Jupiter, despite sharing a similar massive, Jovian girth, orbits so closely that its orbital period is drastically reduced, often lasting mere days or sometimes even hours. This proximity places them inside the orbit of Mercury in our Solar System, which itself takes about 88 Earth days to orbit the Sun, highlighting the extreme nature of the Hot Jupiter's year length.
