Barnard's Star

Project Hail Mary

Begins dimming after the Hail Mary departs Earth. Proof that Astrophage is still spreading even as Grace flies toward Tau Ceti.

Nearby red dwarf with the largest proper motion of any star, just six light-years away. It slides across the sky fast enough that charts need updates over decades.
