TOI-1136 is a G-type main-sequence star 276 light-years (85 parsecs) away in the constellation Draco. It is slightly smaller than the Sun and similar in mass and temperature, but is much younger, with an age of about 700 million years. It hosts a system of at least six, and possibly seven, exoplanets.[3]
