Gliese 163 is a faint red dwarf star with multiple exoplanetary companions in the southern constellation of Dorado. Other stellar catalog names for it include HIP 19394 and LHS 188.^[10] It is too faint to be visible to the naked eye, having an apparent visual magnitude of 11.79^[2] and an absolute magnitude of 10.91.^[2] This system is located at a distance of 49.4 light-years from the Sun based on parallax measurements.^[1] Judging by its space velocity components, it is most likely a thick disk star.^[3]

This is a small M-type main-sequence star with a stellar classification of M3.5V.^[3] It has a relatively low activity level for a red dwarf of its mass, suggesting it is an old star with an age of at least two billion years.^[6] This star has 41% of the mass and radius of the Sun.^[4] It is spinning slowly with a projected rotational velocity of 0.85 km/s^[8] and has a rotation period of 61 days.^[7] The star is radiating just 2%^[6] of the luminosity of the Sun from its photosphere at an effective temperature of 3,460 K.^[4]
