Star in the constellation Phoenix
CD−44 170 , also known asGliese 27.1 ,Gliese 9018 andHIP 3143 , is anM-type main-sequence star . Itssurface temperature is 3,604 K (6,028 °F; 3,331 °C)± 72K . The star'sconcentration of heavy elements is similar to that of theSun .[ 8]
In 2014, a planet named Gliese 27.1 b with an orbital period of 16 days was announced. It was discovered using theradial velocity method .[ 11] [ 6] [ 4]
