Question

The main difference between hot Jupiters and cold Jupiters is their orbital distance from their parent stars. Hot Jupiters orbit very close to their stars, often within 0.05 astronomical units (AU) or less, while cold Jupiters are much farther away, typically beyond the frost line where water can freeze into ice. While hot Jupiters do radiate more energy than they receive from their star, this is not a defining characteristic and there is no evidence of volcanoes on either type of planet. The discovery of both hot and cold Jupiters was significant in advancing our understanding of planetary science, so neither can be considered more or less exciting than the other. Hot Jupiters orbit very close to their parent star, often within 0.1 AU (astronomical units); while Cold Jupiters are farther out with an orbital distance of over 5 AU. This makes the Hot Jupiter's temperature much hotter due to the close proximity to the star, while the Cold Jupiter's are much colder.
