Chthonian planet

Summary
Chthonian planets (ˈkθoʊniən, sometimes 'cthonian') are a hypothetical class of celestial objects resulting from the stripping away of a gas giant's hydrogen and helium atmosphere and outer layers, which is called hydrodynamic escape. Such atmospheric stripping is a likely result of proximity to a star. The remaining rocky or metallic core would resemble a terrestrial planet in many respects. Etymology Chthon (from Χθών) means "earth". The term chthonian was coined by Hébrard, et al., and generally refers to Greek chthonic deities from the infernal underground. Possible examples Transit-timing variation measurements indicate, for example, that Kepler-52b, Kepler-52c and Kepler-57b have maximum masses between 30 and 100 times the mass of Earth (although the actual masses could be much lower); with radii about two Earth radii, they might have densities larger than that of an iron planet of the same size. These exoplanets are orbiting very close to their stars and
