BD-21 784, also known as Gliese 160.2, Gliese 9144, LHS 1628 or HIP 19165 is a K-type main-sequence star located 84.4 light-years away in the constellation of Eridanus. Its surface temperature is 4300 K. The star's concentration of heavy elements is low, with concentration of iron just 55% of the Sun`s. The age of BD-21 784 is poorly constrained to range from 1.1 to 10 billion years, but may be similar to that of the Sun.

Planetary system
In 2014 one planet, named Gliese 160.2 b, was announced on a 5.2-day orbit, discovered by the radial velocity method. The planetary equilibrium temperature is 736$$ K. The existence of the planet was refuted with the expanded radial-velocity dataset in 2020 though.
