43 Persei is a binary star system in the northern constellation Perseus. It is visible to the naked eye as a dim, yellow-white hued star with an apparent visual magnitude of 5.28. The system is located around 38.7 parsecs (126.2 ly) distant from the Sun, based on its dynamical parallax.
This is a double-lined spectroscopic binary with an orbital period of 30.4 days and an eccentricity of 0.6. It has also been spatially resolved with interferometry at the CHARA array. There are distant companions B (separation 75.5" and magnitude 10.66), C (separation 85.6" and magnitude 12.18), and D (separation 68" and magnitude 13.43).
