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. [9]

The primary star's surface temperature is 6325±75 K. [11] HD 175289 is similar to the Sun in its concentration of heavy elements, with a metallicity Fe/H index of 0.01±0.10, [11] but is much younger at an age of 1.81±0.27 billion years. [10]

Planetary system

In 2013, one planet, named Kepler-410Ab, was discovered using the transit method. [14] It is not known if the planet is orbiting the primary or secondary star. [14] If orbiting the secondary, the planetary radius must be doubled. [15] 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. [7]
