Beta Hydri (β Hyi / β Hydri) is a star in the constellation Hydrus (Note that Hydrus is not the same as Hydra).

It is about 24.4 light years away from Earth. Beta Hydri is often studied because it might give insights on what might happen to our Sun in the next 2.5 billion years. It is larger and slightly more massive than the Sun.

At around 150 BC, this star was two degrees away from the southern celestial pole. It is currently the nearest relatively bright star to the southern pole.

Although Beta Hydri is likely to harbor a system of extrasolar planets, no such system has yet been detected
