What is HIP 21743
In Eridanus, the long celestial river, glows a yellow sun whose light set out around 1675, when Newton had not yet published the Principia and modern science was taking root. More luminous and somewhat hotter than our own star, it feels like an elder sibling of the Sun. Its golden glow rests upon a constellation that winds across the sky like a stream without banks.
