what is the new section they cut out of Scorpius to name Orphecus and when, why this happened too?was this nasa that did this or who, when, how decided?
please xplain anything you can too about the stars, star clusters? (WHAT IS DIFFERENCE btw?)
thanks for your answers!Which major stars or "Star clusters" are located in the constellation of Scorpius? and Orphecus?Scorpius contains many bright stars, including Antares (伪 Sco), 尾1 Sco (Graffias), 未 Sco (Dschubba), 胃 Sco (Sargas), 位 Sco (Shaula), 谓 Sco (Jabbah), 尉 Sco (Girtab), 蟺 Sco (Iclil), 蟽 Sco (Alniyat), 蟿 Sco (also known as Alniyat) and 蠀 Sco (Lesath). Most of the bright stars are massive members of the nearest OB association: Scorpius-Centaurus.Due to its location on the Milky Way, this constellation contains many deep sky objects such as the open clusters Messier 6 (the Butterfly Cluster) and Messier 7 (the Ptolemy Cluster), NGC 6231 (by 味虏 Sco), and the globular clusters Messier 4 and Messier 80.
Orphecus is not any Constellation, it is Ophiuchus. The brightest stars in Ophiuchus include 伪 Ophiuchi, called Rasalhague (at the figure's head), and 畏 Ophiuchi.Barnard's Star, one of the nearest stars to the Solar System (the only stars closer are the Alpha Centauri binary star system and Proxima Centauri), lies in Ophiuchus.
Ophiuchus contains several star clusters, such as IC 4665, NGC 6633, M9, M10, M12, M14, M19, M62, and M107, as well as the nebula IC 4603-4604. The unusual galaxy merger remnant NGC 6240 is also in Ophiuchus. In 2006, a new nearby star cluster was discovered associated with the 4th magnitude star Mu Ophiuchi.
Star clusters or star clouds are groups of stars. Two types of star clusters can be distinguished: globular clusters are tight groups of hundreds of thousands of very old stars which are gravitationally bound, while open clusters, a more loosely clustered group of stars, generally contain less than a few hundred members, and are often very young. Open clusters become disrupted over time by the gravitational influence of giant molecular clouds as they move through the galaxy, but cluster members will continue to move in broadly the same direction through space even though they are no longer gravitationally bound; they are then known as a stellar association, sometimes also referred to as a moving group.
Star clusters visible to the naked eye include Pleiades, Hyades and the Beehive Cluster.
A star is a massive, luminous ball of plasma held together by gravity. At the end of its lifetime, a star can also contain a proportion of degenerate matter. Stars are formed within extended regions of higher density in the interstellar medium, although the density is still lower than the inside of an earthly vacuum chamber. These regions are called molecular clouds and consist mostly of hydrogen, with about 23鈥?8% helium and a few percent heavier elements. One example of such a star-forming region is the Orion Nebula. As massive stars are formed from molecular clouds, they powerfully illuminate those clouds. They also ionize the hydrogen, creating an H II region.
There are different single-letter classifications of stars according to their spectra, ranging from type O, which are very hot, to M, which are so cool that molecules may form in their atmospheres. The main classifications in order of decreasing surface temperature are: O, B, A, F, G, K, and M. A variety of rare spectral types have special classifications. The most common of these are types L and T, which classify the coldest low-mass stars and brown dwarfs. Each letter has 10 sub-divisions, numbered from 0 to 9, in order of decreasing temperature. However, this system breaks down at extreme high temperatures.
Hope that Helps!!!!Which major stars or "Star clusters" are located in the constellation of Scorpius? and Orphecus?To add to Ian's excellent answer. Ophiuchus is nothing new. It is at least 4,000 years old and was known by the ancient Greeks. In fact Scorpius is younger because Scorpius was a part of Libra just 2,000 years ago.
This is well before Nasa, because Nasa is just some 50 years old.
