HD 175289
HD 175289 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]
Planetary system Edit
In 2013, one planet, named Kepler-410 Ab, was discovered using the transit method.[10] It is not known if the planet is orbiting the primary or secondary star.[10] If orbiting the secondary, the planetary radius must be doubled.[11] Immediately, a second non-transiting planet was suspected due to transit-timing variations, and a 2019 study also found evidence for such a planet, though it has not yet been confirmed or given any designation.[12]
