BD−08°2823 is a star with a pair of exoplanetary companions in the faint equatorial constellation of Sextans. The star has an apparent visual magnitude of 9.86, which is too faint to be visible with the naked eye. This system is located at a distance of 135 light-years from the Sun based on parallax measurements, and is trending further away with a radial velocity of +53 km/s. It is a high proper motion star that is traversing the celestial sphere at the angular rate of yr−1.

This is an ordinary K-type main-sequence star with a stellar classification of K4:V, where the ':' notation indicates some uncertainty. Emission cores in the H and K lines suggest this is an active star, with the level of activity varying significantly over time. It is roughly five billion years old and is spinning with a projected rotational velocity of 1.4 km/s. Measurements of the activity variation suggest a rotation period of around 27 days. This star is smaller, cooler, and less massive than the Sun. Its metal content is slightly lower than in the Sun. The star is radiating 24% of the luminosity of the Sun from its photosphere at an effective temperature of 4,746 K.
