 | Beta Hydri (of the constellation Hydrus, not Hydra) is the closest subgiant (G2 IV) and one of the oldest stars in the solar Galactic neighborhood. |
| A relatively high lithium abundance of Beta Hydri may be a signature of the early subgiant stage, when lithium that once diffused to beneath the main-sequence convection zone, is dredged up to the surface as the convection zone deepens. |
| For Beta Hyi, the average profile over twelve years is shown (bold), while the dotted curve is the spectrum of integrated sunlight, as revealed by an IUE observation of the Moon with nominally identical instrumental settings. |

| Beta Hydri (β Hyi / β Hydri) is a star about 24.4 light years away from Earth. |
| Make sure not to confuse "Hydri" with "Hydra." It's the second brightest star in the constellation Hydrus (the water snake) hence the beta part of it's name. |
| Beta Hydri is often studied because it might give insights on what might happen to our sun in the next 2.5 billion years. |
