HD 88218

HD 88218 (HR 3992) is a binary star in the southern constellation Antlia. The system has a combined apparent magnitude of 6.14, making it faintly visible to the naked eye. HD 88218 is relatively close at a distance of 103 light years but is receding with a heliocentric radial velocity of $$.

The visible component has a stellar classification of G0 V, indicating the object's status as a solar analogue. As for the companion, it is probably a K-type star based on a mass of $$. As of 2018, both stars have a projected separation of $$ along a position angle of $$. The system has an orbital period of 86.6 years.

Despite the class described above, the primary is starting to evolve off the main sequence at the age of 6.8 billion years, having a low surface gravity and a slightly enlarged radius of $$, with the addition of being chromospherically inactive. Nevertheless, it has 107% the mass of the Sun and radiates at 2.88 times the luminosity of the Sun from its photosphere at an effective temperature of $$, giving a yellow glow. HD 88218 A has an iron abundance 72% that of the Sun and spins leisurely with a projected rotational velocity of $36.7 km/s$.
