Kepler-410 is a binary star system. Its primary star, also known as Kepler-410A, is a F-type subgiant star, orbited by the orange dwarf star Kepler-410B on a wide orbit. The companion star was discovered in 2012.[6]
The primary star's surface temperature is 6325±75 K.[8] HD 175289 is similar to the Sun in its concentration of heavy elements, with a metallicity Fe/H index of 0.01±0.10,[8] but is much younger at an age of 1.81±0.27 billion years.[7]
