Nu-1

Its story

Nu-1 Lupi drifts across the sky faster than most of its neighbours, an F-type subgiant 117 light-years away in the southern reaches of the Wolf. About two billion years old, with nearly 1.7 solar masses and metallicity above the Sun's, it emits a faint X-ray glow. Despite its modest brightness, its high proper motion turns it into a silent witness to the slow turning of the galaxy.
