Both planets are considered to be good targets for transmission spectroscopy measurements for determination of atmospheric composition.
[2] It is a single star with stellar companions ruled out by sky surveys, speckle imaging and the radial velocity method.
[2] Both planets are sub-Neptunes, similar in size, expected to have atmospheres with a significant fraction of hydrogen and helium.
[2] As of January 2025[update], the planets' masses have not yet been directly measured, though their masses estimated based on the empirical mass–radius relationship were noted in the discovery paper to fall above the limits of detection for the radial velocity method.
However, the limited observations available by the time of the discovery paper were only adequate to rule out deviations by more than 5 min from linear ephemerides.
