Tau Centauri

It is visible to the naked eye with an apparent visual magnitude of +3.86.

[2] The distance to this star, based upon an annual parallax shift of 24.85 mas,[1] is 131 light years.

There is a 98% chance that it is a co-moving companion of Gamma Centauri; the two stars have an estimated separation of 1.7 ly (0.53 pc).

It is around 132[7] million years old and is spinning rapidly with a projected rotational velocity of 296.8[9] km/s.

This is giving the star an oblate shape, with an estimated equatorial girth that is 30% larger than the polar radius.
