An interesting question: if you look up in the Earth’s sky with the naked eye, assuming you have a healthy vision, how far away can you see? Could you see beyond the Milky Way galaxy, for example?
Andromeda Galaxy is the farthest object in the sky that we can see with the naked eye. It is approximately 2.5 million light-years (770 kiloparsecs) from Earth and the nearest large galaxy to the Milky Way.
So, you can see 2.5 million light-years away if you look in the sky with the naked eye.
2.5 million light-years distance is equivalent to about 23.65 billion trillion kilometers (2.36×1022 km) or 14.7 billion trillion miles (1.47×1022 mi).
1 billion trillions = 1 sextillion
