Gliese 393, or GJ 393, is a single[7] star with an orbiting exoplanet companion in the equatorial constellation of Sextans, positioned about 1.5° to the NNW of Beta Sextantis.
This star is located at a distance of 22.9 light years from the Sun based on parallax,[1] and is drifting further away with a radial velocity of +8.3 km/s.
[2] It shares a similar space motion as members of the AB Doradus moving group, but is considered a random interloper.
[5] The stellar classification of GJ 393 is M2V,[3] indicating this is a small red dwarf star that is generating energy through core hydrogen fusion.
It is radiating just 2.7% of the Sun's luminosity from its photosphere at an effective temperature of 3,579 K.[3] In 2019, one candidate planet was detected by the radial velocity method.
