It is too faint to be visible to the naked eye with an apparent visual magnitude of 8.07.
Prior to the discovery of a companion, this served as an IAU radial velocity standard,[7] and it is receding from the Sun at a rate of +37 km/s.
[2] It is radiating 1.3 times the Sun's luminosity from its photosphere at an effective temperature of 6,090 K.[5] The detection of an orbiting companion, designated HD 140913 B, was announced in 1994.
Alternatively, it may be an under-mass helium white dwarf that has lost its envelope during a mass transfer.
[10] It orbits the host star about every 148 days with an eccentricity (ovalness) of ~0.57 and a semimajor axis of at least 0.55 AU.
