Lambda Hydrae
What is Lambda Hydrae
λ Hydrae shines amber from 113 light-years, a K-class star in the long-stretched head of Hydra, the largest constellation in the sky. Its warm hue marks a mature sun — cooler than ours yet far larger — in a calm phase of its evolution. It moves quietly within a procession of unnamed stars that winds across nearly a quarter of the celestial vault.
