hot Jupiter
noun1
Astronomy, Natural sciences, Planetology An exosolar planet whose characteristics are similar to Jupiter, but which orbits its parent star much more closely and thus has higher temperatures.
- Or, to put it a different way, the chance of finding a hot Jupiter is 100 times higher than the chance of finding a normal Jupiter, because it is 100 times closer to its parent star.2010, James Kasting, How to Find a Habitable Planet, Princeton, N.J.: Princeton University Press, →ISBN, →LCCN, →OCLC, page 224:
