The population of known transiting exoplanets compared to K2-416 b, K2-417 b, and EPIC 246251988 b. We show the population of exoplanets in period/radius space, since these are the most readily measured observables for transiting planets like these objects. The grey points are planets other than the ones shown here, and the size of the symbol is proportional to the size of the planet’s host star. K2-416 b and K2-417 b are shown in red, since their hosts are M-dwarfs, while EPIC 246251988 b is shown in orange to represent its G-dwarf host. The periods and radii of these three planets are typical of other small transiting planets discovered by Kepler and TESS.
