Please help me write down the names of 20 galaxies and their constellations and stars!

You've got the size relationship wrong. With the naked eye, this galaxy is very small, except for the Andromeda galaxy M3 1 and the Magellanic Cloud, others are invisible to the naked eye. The apparent area is much smaller than the size of the constellation. We should say which constellation contains which stars and galaxies. If you ask, I can write some for you. But the number of galaxies discovered now is astronomical, and you can't write down the names of all the galaxies. And the names of galaxies are generally numbered, such as NGC catalog, IC catalog, UGC catalog and so on.

There are a lot of things these two days, so I can only write you a few from memory. If it is still too small, please contact me again:

1, Andromeda:

Yinhe M3 1, NGC22 1

Xing Xing Soapy II

2. Ursa major:

Galaxy M8 1

Stars are,, celestial pole, Tian Quan, Yuheng, Kaiyang, Yaoguang (above is the Big Dipper), and Kaiyang has a companion star named Fu.

3.leo:

Galaxy Murphy 1, Murphy 2

Five emperors star Xuanyuan no.14 building 1

4. Virgo:

Galaxies M87 and M 104

Xingjiao Ju Chi

5. Centauri:

Yinhe NGC5 128

Xing xing nan men er

6. Triangle:

Yinhe M33

The stars can't remember clearly for the time being.

7. cans:

The stars can't remember clearly for the time being.

I'll write these for you temporarily.
