LHS 2090 is a red dwarf star of spectral type M6.5V, located in constellation Cancer at 20.8 light-years from Earth.

[10] The star was identified to be a red dwarf at short distance (6 parsecs from Sun) in 2001.

[11] As typical for very cool red dwarfs, its spectrum is dominated by molecular water absorption.

Stellar metallicity is similar to that of Sun`s.

[8] Radial velocity measurements did not yield any detection of stellar companion or giant planet on orbit around LHS 2090, as in 2018.
