What term describes gas giant exoplanets that orbit very close to their stars?

• A. Terrestrial planets
• B. Hot Jupiters
• C. Super-Earths
• D. Ice giants

Answer: (B)

The concept tested is that some gas giants orbit very near their stars, and the term used for those is hot Jupiters. Hot Jupiters are gas giants like Jupiter, but they reside very close to their star, often very close in astronomical terms, so their atmospheres become extremely hot. This close distance leads to strong stellar irradiation and often tidal locking, which affects their appearance and how we detect them. Other labels describe different kinds of planets: terrestrial planets are rocky and small, not gas giants; Super-Earths are larger rocky worlds; ice giants are large, volatile-rich planets like Uranus and Neptune that generally orbit farther from their star. So the term that specifically describes these close-in gas giants is hot Jupiters.
