"Previous astronomical surveys have detected at least three exoplanets that may be eggshell planets, Byrne said. Although scientists are a long way from directly imaging the surfaces of these eggshell planets, he noted they might resemble the lowlands on Venus, which contain vast expanses of lava but have little high-standing terrain, because the lithosphere there is thin as a result of scorching surface temperatures."

I checked the reference links. It would be good to spell out what these 3 eggshell exoplanets are by their names. We have many to select from at these two sites. The Extrasolar Planets Encyclopaedia (exoplanet.eu) , and NASA Exoplanet Archive (caltech.edu)
