From the explanation

“The most distant object easily visible to the unaided eye is M31 , the great Andromeda Galaxy . Even at some two and a half million light-year s distant, this immense spiral galaxy — spanning over 200,000 light years — is visible, although as a faint, nebulous cloud in the constellation Andromeda .”
