Gliese 784 is a single[8] red dwarf star located in the southern constellation of Telescopium that may host an exoplanetary companion.

The star was catalogued in 1900, when it was included in the Cordoba Durchmusterung (CD) by John M. Thome with the designation CD−45 13677.

[2] Gliese 784 is located at a distance of 20.1 light-years from the Sun as determined from parallax measurements, and is drifting closer with a radial velocity of −33.5 km/s.

It is radiating just 6%[5] of the luminosity of the Sun from its photosphere at an effective temperature of 3,754 K.[6] In June 2019 one planet candidate was reported in orbit around Gliese 784.

[12] An infrared excess was detected in 2020 that could suggest the presence of a circumstellar disk, but this is likely due to a background galaxy.
