136 Tauri is a white-hued binary star system in the zodiac constellation of Taurus. It has a combined apparent visual magnitude of 4.56, which is bright enough to be faintly visible to the naked eye. Based upon an annual parallax shift of as seen from Earth's orbit, it is located approximately 420 light years from the Sun. The system is moving nearer with a heliocentric radial velocity of −17.2 km/s, and is expected to make its closest approach in 6.5 million years at a distance of 45order=flipNaNorder=flip.
This is a close, double-lined spectroscopic binary with an orbital period of 5.96 days and an eccentricity of 0.00. Tidal effects between the pair may have circularized their orbit and slowed their rotation rates – the primary has a projected rotational velocity of 10 km/s. They have a combined stellar classification of A0 V, and both are most likely A-type main-sequence stars of the same class.
