Unicorn _ What is Unicorn?

One of the zodiac signs. Located in the south of Gemini and the north of Canis Canis, in the Milky Way between Canis Canis and Orion. However, this part of the Milky Way is located at the edge of the Milky Way, so it is far less bright than the Milky Way in summer. The most beautiful celestial body in Kirin constellation is the Rose Nebula (also known as the Rose Nebula, NGC2237, with a visual magnitude of about 6). In the center of this dim rose-red nebula, there is an open cluster (NGC2244), which consists of more than a dozen turquoise and golden stars. Unfortunately, this rose in the sky can't be seen directly from the telescope, and its color can only be seen in the photos taken with the telescope for a long time. As early as the Persian map, there are already pictures of this constellation. However, its image is completely different from that of Kirin in China mythology. It is a unicorn in the shape of a white horse, and its first horn is located in the east of Orion, just "cut" by the Milky Way. There are few bright stars among them. Every year on the night of 65438+10.5, the unicorn constellation reaches the zenith, and10 and February are the best months to observe it. Unicorn is Monoceros in Latin, which means unicorn or rhinoceros. Astronomers in China translated it into Kirin. Kirin is a mythical animal, and the unicorn depicted in ancient legends in China is bijuu, a one-horned deer. The whole body is covered with scales, which was used by the ancients to symbolize auspiciousness, so Kirin is called an auspicious constellation. Unicorn is equivalent to China's Sidu, Queqiu and other star officials. The alpha star in the unicorn, whose Chinese name is Que Masi Oka VII, is a KO ⅲ red giant with a magnitude of 3.93 and a distance of 180 light years. The beta star of Kirin (Betelgeuse 26) is a triad star with a synthetic magnitude of 4.2, a sub-star of 4.7 and a sub-star of 5.2. Substar c is 6. 1 etc. Kirin (Betelgeuse 28) has an apparent magnitude of 3.98 and a distance of 220 light years. The apparent magnitude of δ star in Kirin constellation (Chinese name Queqiu II) is 4. 15, and the distance is 220 light years. Stars numbered unicorn 15 (brightness is 4.7, etc. ) also known as unicorn s type. It is a Liuhe star, and its sub-stars are A star 4.8, B star 7.6, C star 9.9, D star 9.7, E star 10.0, F star 7.8 and so on. Unicorn star S is located in an open cluster NGC 2264, 2700 light years away. Surrounding the cluster is a huge fuzzy diffuse nebula. NGC 2264 open cluster is surrounded by complex and chaotic cosmic gas and dust, which is mixed with red luminous cloud gas, which is excited by high-energy light emitted by newly formed stars in dark cloud gas. Around the shape, interstellar dust covering the star reflects starlight to form blue reflection cloud gas.
