LTT 1445 is a triple M-dwarf system 22.4 light-years (6.9 parsecs) distant[1] in the constellation Eridanus.

[2] The TESS light curve showed stellar flares and rotational modulation due to starspots, likely on either the B or C component.

Astrophysicists of the Harvard Center for Astrophysics discovered it in June 2019 with data from the Transiting Exoplanet Survey Satellite.

[7][2] The team obtained follow-up observations, including HARPS radial velocity measurements to constrain the mass of the planet.

[10] LTT 1445 Ab likely has a rocky composition, and because it orbits close to the M-dwarf, it has an equilibrium temperature of 431±23 K (158 °C; 316 °F).
