Question 2: Which constellation does the solar system belong to? Does not belong to any constellation. See baike.baidu/view/884018.
Question 3: Which constellation cantilever is the solar system on? First, correct a misunderstanding. Constellation is just a projection of the sky where some stars are located, not a celestial system, but an area on the celestial sphere. So it can't be said that there are several constellations in the Milky Way. On the contrary, constellations often contain many galaxies (such as Virgo cluster and late constellation cluster). , they all contain thousands of galaxies). Because we are in the Milky Way, our ability to describe it is limited. I only provide the latest research results, and I can't completely guarantee the correctness, but what I provide is definitely the most accurate information at present. The shape of the Milky Way has always been controversial, and it was not until 2004 that it was confirmed that there was a rod-like spiral galaxy in the nuclear sphere. 195 1 year, scientists first discovered that the Milky Way has three spiral arms. Later, in the 1960s and 1980s, the structural drawings drawn by the radio telescope thought that it had four spiral arms: rectangular spiral arm, shield-Centauri spiral arm, Sagittarius spiral arm and Perseus spiral arm. Our solar system is located in a smaller Orion spiral arm, which lies between Sagittarius and Perseus. Recently, with the help of Spitzer's high-definition pictures of the Milky Way, astronomers found that the number of stars on the spiral arm of the shield-Centauri is increasing, which is the characteristic of the spiral arm. Usually, the spiral arms of spiral galaxies contain a lot of dust and nebulae, so many stars will be born from them. But Sagittarius and the rectangular spiral arm did not find the increase in the number of stars, and Spitzer could not see it, because the Perseus arm extended to the other side of the galaxy. Based on this, researchers believe that there are only two main spiral arms in the Milky Way: the shield-Centauri spiral arm and the Perseid spiral arm, among which young bright stars and old red giants are the most dense. As shown in the figure, the two rotating arms are respectively connected with the star rod in the center of the nuclear sphere. Hiphotos.baidu/...a3.jpg added: If you mean a galaxy like the solar system, according to scientists' calculations, a star with too much mass has a very short life span, and a star with 60 times the mass of the sun has only a few million years, so it is generally impossible to form a complete planetary system. More than half of the stars with the same mass are binary stars, so the probability of such stars forming a planetary system is much smaller. Moreover, only half of the stars that meet these conditions will be surrounded by planets, so according to this calculation, there should be no more than 654.38+000 billion solar-like galaxies in the Milky Way.
Question 4: Which constellation does my solar system belong to? Milky Way
Question 5: Is Orion bigger or the solar system bigger? Orion is a constellation, which is what we call a region in the sky. Because the bright stars in the sky make up the appearance of Orion, it is called Orion.
All the stars in Orion that we can see with the naked eye are in the Milky Way, and the distance is very different, but they are all in the same direction of the earth, and we seem to be very close. The solar system, including the earth, is just an ordinary small star and its planetary system.
A cantilever of the Milky Way is in the direction of Orion, so it is called Orion spiral arm. In the sky of Orion, we can also see an extragalactic galaxy, which we call the Orion Nebula. In fact, it is a galaxy on the same level as the Milky Way, which is very far from the whole Milky Way.
