The exoplanet HD 209458b has a mass more than 200 times Earthт??s and has a diameter greater than Jupiterт??s. It orbits its star at about an eighth of the distance Mercury orbits the sun, so the exoplanet takes only 3.5 days to complete an orbit. This proximity to a star means that the planet is hot, perhaps 1000ТАC, hence it is classed as a т??hot Jupiterт?? ...

... There has been a heated public discussion in the past few years about whether our ninth planet is really deserving of the name. Since Pluto orbits a star, and is much less luminous, it certainly satisfies the definition we have above. The problem is actually not with Pluto, but with a very large number of other bodies in our Solar System which also satisfy this definition, but which are not called planets. Perhaps the most notable of these is Ceres, the largest asteroid. ... Planet . ...
