Gliese 69 is a star located in the constellation of Cassiopeia. It has an apparent magnitude of 8.40. [2] Parallax measurements by Hipparcos put it at a distance of 44.3 light-years (13.6 parsecs) away. [1]
Gliese 69 is a K-type main-sequence star that is smaller and less massive than the Sun. [5] It glows with an effective temperature of 4,312 K. [6] It is around 6.9 billion years old, [6] significantly older than the Sun. Gliese 69 is also known by its designations HD 10436 and LHS 1291. [7]
In 2019 one candidate planet been detected by the radial velocity method. [8]
