Citando:
"The exoplanet, called GJ 3470b, is located near what researchers call the “Hot Neptune Desert” around its host star. Scientists believe that there’s a lack of such planets because they are completely destroyed over time due to their close relationship with the stars they orbit, and GJ 3470b might be the next to go.

One of GJ 3470b’s fellow planets is GJ 436b, which astronomers believe is losing its atmosphere as its star strips it away. Scientists think that 436b will survive the ordeal without being completely destroyed, but 3470b is in a much tougher spot. 3470b is being stripped of mass 100 times faster than 436b, and it’s possible that the planet will be completely vaporized."
