What type of galaxy is the Milky Way in which Earth is located? ?, Where is the earth an integral part of the solar system, and the earth and all other bodies in the solar system revolve around the sun, and the solar system and therefore the sun and the earth are located in the Milky Way galaxy, so from this standpoint we will learn about what type of galaxy is the earth in?
Solar System
The solar system and Earth are located about 25,000 light-years away from the center of the Milky Way galaxy, and 25,000 light-years from the edge, where the Milky Way galaxy is the place that is located approximately halfway between the center and the edge, and astronomers say it is agreed that the galaxy The Milky Way contains mostly two main spiral arms, which are the Perseus arm and the Scutum-Centaurus arm, with many small arms and protrusions, as the solar system is located in the region between the arms, and this arm is 3,500 light-years wide and 10,000 light-years long when detached from the bow arm. The Milky Way galaxy is characterized by a relatively low brightness due to the gases and dust that fill the galaxy disc, and this prevents us from seeing the bright center of the galaxy or from noticing what is on the other side of it clearly.
What type of galaxy is the Milky Way in which Earth is located?
When traveling outside the galaxy and looking at it from above, it will be noted that the Milky Way galaxy is a narrow spiral galaxy, for the longest period, so it is of the type of Milky Way galaxy in which the Earth is located. spiralIt was thought that the Milky Way had 4 spiral arms, but the latest surveys have found that it actually has two spiral arms, called Scutum-Centaurus and Carina-Sagittarius, in addition to astronomers now estimate that there are between 100 and 400 billion stars in the Milky Way . And every star has at least one planet, which means there are probably hundreds of billions of planets in the Milky Way, it is also thought. And billions of them are the size and mass of Earth.
The size of the Milky Way
The Milky Way galaxy is very large, with a diameter ranging from 100,000 to 120,000 light-years, a thickness of about 1,000 light-years, and up to 400 billion stars inside it, and since one light-year is about 9.5 x 10^12 kilometers (9.5 trillion kilometers) The Milky Way is about 9.5 x 10^17 to 11.4 x 10^17 km, or 9,500 to 11,400 quadrillion kilometers across, and it got to its present size and shape by gobbling up other galaxies, and continues to do so to this extent. day. In fact, the Canis Major Dwarf Galaxy is the closest galaxy to the Milky Way because its stars are currently being added to the Milky Way.
At the end of this article, we summarize the most important points in it What type of galaxy is the Milky Way in which Earth is located? What are its most important characteristics and features, and what is its size? It is one of the most important features of this universe.
