OGLE-TR-123 is a

main-sequence stars whose radius has been measured. It was discovered when the Optical Gravitational Lensing Experiment (OGLE) survey observed the smaller star eclipsing the larger primary. The orbital period is approximately 1.80 days.[3]

OGLE-TR-123B

The smaller star, OGLE-TR-123B, is estimated to have a

solar radii, and a mass of around 0.085 solar masses (M☉), or approximately 90 times Jupiter's. OGLE-TR-123b's mass is close to the lowest possible mass, estimated to be around 0.07 or 0.08 M☉, for a hydrogen-fusing star.[4]
