There are two constellations on the connecting line between the Patriarch Horn of Lyra and Vega, one is the Nordica Corona, and the other is the Five Immortals near Vega. You can also find Ursa by connecting Alpha Cygnus and Vega and extending them to twice the distance. Hercules was a hero in the world before his death, but he was very modest in heaven and didn't want to pretend to be a prominent figure. Therefore, Perseus is not significant, and the brightest star is only 3m.

This is a map of Hercules. Look, Hercules is kneeling on his right leg, with a big stick in his right hand and Hydra in his left hand. How spectacular! Interestingly, the image of Hercules looks upside down in the northern hemisphere, and only in the southern hemisphere can it be seen as upright as this map.

Near the star η between η and ζ in Ursa major, there is a famous large galaxy cluster, Ursa major. Its brightness is equivalent to 4m, so we can see it on a clear moonless night. This large cluster of galaxies is 34,000 light years away. It is spherical with a diameter of over 65,438+000 light years. The farther you go, the denser the stars are. At the center, the density of stars is hundreds of times that of stars near the solar system. Astronomers estimate that it has more than one million members, many of whom cannot be seen through large telescopes.

Our sun is a star, but it is also moving. It not only "revolves" around the center of the Milky Way like other members of the Milky Way, but also takes us to Wu at a speed of about 19.5 kilometers per second.
