TOI-6692 b is a confirmed exoplanet orbiting a G1 spectral class yellow dwarf or subgiant star, TOI-6692, at a distance of approximately 1013 light-years from the Sun. The discovery of the object was officially announced by an international team of astronomers led by Allison Bieri in late January 2026. This exoplanet was detected using the transit method.
The planet is a giant planet, with a mass of approximately 0.62 MJ and a radius of about 1.04 RJ. It orbits its host star at a distance of 0.512 AU, which is roughly half the distance from Earth to the Sun. One year on the planet is approximately 131 days. However, its orbit is highly eccentric, with an orbital eccentricity of 0.537. Its orbital inclination is 89.483°. The equilibrium temperature is estimated to be 467 K, or about 194 °C.
Astronomers note that TOI-6692 b is one of only a few giant planets with an orbital period exceeding 100 days for which both mass and radius have been measured. Furthermore, they add that this planet is also one of the few single-transit TESS targets whose period has been definitively confirmed through subsequent photometric follow-up.
