I think we don’t know exactly that which is the smallest star as we haven’t found 1 % of the stars in the milky Way, but OGLE-TR-122 is the smallest known star.
The “OGLE-TR-122” which is a binary stellar system is the smallest known star in our solar system. Its expected radius is about 0.12 solar radii which is approximately 120 percent of the radius of Jupiter (largest planet in our solar system). It has the mass of about 0.1 solar masses which is very close to the lowest possible mass i.e. 0.07 solar masses.
