The brightest star in the summer sky in the northern hemisphere?

It seems that the three answers upstairs feel very different, and the word "one voice" may be difficult to determine.

The first floor is basically correct. I'm afraid what I said on the second floor was a little thoughtless, and the third floor only answered half of it.

Add the answer on the first floor.

Now, after sunset, you can see the following celestial bodies (there must be more than three). Give the landlord a way to adapt to the darkness 15 minutes of darkness. In this way, the pupil can be enlarged by about three times, and the light gathering ability is ten times that of the original. Being in Shanghai, the light pollution situation is probably much more serious than that of the landlord. But you can still see hundreds of stars in the shadows of homes and schools in cities.

In the west, you can see three bright stars in a straight line, followed by Venus, Mars and Saturn from west to east.

Look at the sky overhead. In the north, you will see the Big Dipper, and along the bucket handle, you can see arcturus and Kakuji. Typical spring starry sky.

In the east, you can see a triangle, which is the summer triangle, and the brightest star is Vega. Later, the starry sky in summer will replace the starry sky in spring to reach the zenith.

The following is the starry sky in Shanghai at 8 o'clock tonight. I made some comments. Shandong and Shanghai are basically the same, and the observation accuracy with naked eyes can be directly used.
