Can you see Andromeda from the earth?

Of course. The picture below is a photographic work of Andromeda starry sky (the brightness of the stars of Pisces, Aries and Fairy is artificially raised), which is in good condition and can be observed by the naked eye.

Astronomers who are a little farther away can answer that Andromeda is an important constellation in the autumn sky, located in the northwest of Pegasus. Extending from the northeast corner of Pegasus quadrangle, the connecting lines of the four second-and third-order stars are obviously bright (the four bright stars in the picture below are Abigail II, Quesuwu, Milac and General Tian from right to left). However, if you count the dark four stars, the shape is a bit messy, and it is not easy to see the fairy's character, and the constellation connection methods of various factions are also obviously different.

Besides, please use your head. If a starry sky is invisible to the naked eye, how did the ancients associate it in turn and become a constellation? In other words, under good observation conditions, any constellation can be observed with the naked eye all day.

The picture came from the network and has been deleted.
