The planets around LHS 1903, a cool faint red dwarf star, begin as expected with a rocky planet orbiting close by and then two gas worlds. ESA’s CHaracterising ExOPlanet Satellite (CHEOPS) then reveals a surprising fourth planet at the system’s outer edge which is rocky, rather than gaseous.

It sound like Pluto.
