What is the most distant object visible to the naked eye from Earth?

The Andromeda Galaxy is the most distant object visible to the naked eye, located approximately 2.5 million light-years from Earth. Under dark skies, it appears as a faint, misty patch of light, even though it contains roughly one trillion stars. As the nearest major galaxy to our own, the Milky Way Galaxy, Andromeda is one of the most awe-inspiring sights in the night sky. Light from the galaxy began its journey toward Earth about 2.5 million years ago, long before the earliest humans appeared on the planet. Its distance makes it an extraordinary celestial landmark.
