HD 260655

HD 260655 (also known as GJ 239 or TOI-4599)[2] is a relatively bright and cool M0 V red dwarf star located 33 light-years (10 parsecs) away from the Solar System in the constellation of Gemini.

Both planets were detected by the TESS mission and confirmed independently with archival and new precise radial velocity data obtained with the HIRES observatory since 1998, and the CARMENES survey instruments since 2016.

[2] The star is among the earliest-type M dwarfs in the night sky.

[2] Other designations of HD 260655 include Wolf 287, GJ 239, TOI-4599, HIP 31635 and LHS 1858.

[2] Both planets are ideal candidates for future study of exoplanet atmospheres due to their closeness and their bright red dwarf star.
