Even though many of the planets orbit their stars very closely and have high temperatures, which in turn causes their hydrogen - rich atmospheres to expand and a fraction of the gases to escape the planet over time, it's unlikely that the planets will lose enough of their atmosphere to become rocky bodies like Earth, the researchers report online today in the Monthly Notices of the Royal Astronomical Society.
