Andromeda Galaxy - M31

Size
The Andromeda Galaxy is our nearest galactic neighbor - a mere 2.5 million light years away.
It's the most distant object one can see with the unaided eye.
It's dim, so you need a reasonably dark rural sky to spot it.
But, it's also huge.
If you could actually see the whole galaxy in the night sky, it would stretch across the width of 6 full moons.
