CD-44 170
CD-44 170, also known as Gliese 27.1, Gliese 9018 and HIP 3143, is an M-type main-sequence star. Its surface temperature is K. The star's concentration of heavy elements is similar to that of the Sun. Planetary system. In 2014, a planet named Gliese 27.1 b with an orbital period of 16 days was announced. It was discovered using the radial velocity method. The planetary equilibrium temperature is . The planet's existence was doubted until 2020 because the putative orbital period is equal to half of the star's rotational period.
