What constellation is the Milky Way in _ What constellation is the Milky Way in?
The Milky Way intersects the celestial equator in Aquila and is located in the northern hemisphere.
The milky way draws a band with different widths on the celestial sphere, which is called the galactic band. Its widest place is 30, and its narrowest place is only 4 ~ 5, with an average of about 20, which is only a part of the Milky Way.
The Milky Way can only be seen on a clear night, which is caused by the light of countless dark stars. The Milky Way is not the Milky Way, but a part of it. The Milky Way contains hundreds of billions of stars, with a total mass of about 600 billion to 3 trillion times that of the sun and a diameter of about 654.38+ million light years.
Extended data:
The rotation of the Milky Way:
Galactic stars can be divided into more systems according to their distribution, and the stars on the galactic plane rotate rapidly around the center of the galaxy. Stars distributed at a considerable distance above and below the Milky Way galaxy rotate slowly. The sun belongs to the former system, so most of the stars in the latter system are opposite to our solar system, which is why there is such asymmetry. At the same time, we know that only when the stars near the center of the Milky Way rotate faster than the solar system can we observe the position of the center of the Milky Way.
The rotation of a galaxy is directly related to its mass. The closer the angular velocity is to the center of the galaxy, the faster it is. When the distance from the sun to the center of the galaxy is half, the rotation will double and the angular velocity will increase several times. According to this rotation rate, the mass of the galaxy is highly concentrated inside, and the density will decrease outside.
