HD 89571

HD 89571 (HR 4062) is a binary star located in the northern circumpolar constellation Camelopardalis. It is faintly visible to the naked eye with a combined apparent magnitude of 5.51 and is estimated to be 142 light years away from the Solar System. However, it is receding with a heliocentric radial velocity of $$.

The primary has a stellar classification of A9 V, indicating that it is an ordinary A-type main-sequence star. David S. Evans gave it a slightly warmer class of A6 V while Cowley et al. classified it as F0 IV, indicating a F-type subgiant. Nevertheless, the two components take roughly 2 years to orbit each other at a mean separation of $$.

The components have masses of $$ and $$, with the latter being a probable M-type star. HD 89571 has a radius of $$ and a luminosity of $$. This yields an effective temperature of $3.5 km/s$, giving a white hue. It is estimated to be 710 million years old and spins rapidly with a projected rotational velocity of $14.2 mas$; it has a near solar metallicity, equating to an iron abundance 110% that of the Sun.
