HD 192263 is a K1/2V star 64 light-years away. A trailing V marks a main-sequence dwarf, and a K-type star is cooler than the Sun. The star's reported mass estimate is 0.8 solar masses, smaller than the Sun's, and its reported radius estimate is 0.77 solar radii, also smaller than the Sun's. Its reported temperature is 4980 K, cooler than the Sun's, and its age is 2.56 billion years. One planet is known to orbit this host.
That planet, HD 192263 b, was discovered in 1999 by the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion; repeated wobbles reveal the planet and its orbital period. The planet's minimum mass is 178 Earth masses, a lower bound on its true mass that is larger than Earth's, and its orbital period is 24.4 days.
