picture info	Star A star is an astronomical object comprising a luminous spheroid of plasma (physics), plasma held together by its gravity. The List of nearest stars and brown dwarfs, nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night sky, night, but their immense distances from Earth make them appear as fixed stars, fixed points of light. The most prominent stars have been categorised into constellations and asterism (astronomy), asterisms, and many of the brightest stars have proper names. Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations. The observable universe contains an estimated to stars. Only about 4,000 of these stars are visible to the naked eye, all within the Milky Way galaxy. A star's life star formation, begins with the gravitational collapse of a gaseous nebula of material composed primarily of hydrogen, along with helium and trace amounts of heavier elements. Its stellar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Gamma Coronae Australis Gamma Coronae Australis (γ CrA), is a binary star located in the constellation Corona Australis. The system has a combined apparent visual magnitude of 4.20, making it faintly visible to the naked eye. It is located 56.4 light-years (17.3 parsecs) from the Sun, based on its parallax. Gamma Coronae Australis is a member of the Milky Way's thin disk. The system is a visual binary, where the orbit is calculated from observations of one star orbiting the other. The primary, Gamma Coronae Australis A, is a late F-type main-sequence star with an effective temperature of 6,090 K. It has an absolute an absolute magnitude of +3.73, and a mass of 1.15 solar mass The solar mass () is a standard unit of mass in astronomy, equal to approximately . It is often used to indicate the masses of other stars, as well as stellar clusters, nebulae, galaxies and black holes. It is approximately equal to the mass ...es. The secondary, Gamma Coronae Australis B, is also F-type. With an e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	HD 175219 HD 175219, also known as HR 7122, is a solitary, orange hued star located in the southern constellation Corona Australis. It has an apparent magnitude of 5.35, allowing it to be faintly visible to the naked eye. The object is located relatively close at a distance of 314 light years based on Gaia DR3 parallax measurements but is drifting closer with a heliocentric radial velocity of . At its current distance, HD 175219's brightness is diminished by 0.26 magnitudes due to interstellar dust. It has an absolute magnitude of +0.57. This is a red giant with a stellar classification of K0 III. An earlier source gives it a class of G6 III-IV, indicating that it is an evolved G-type star with a luminosity class intermediate between a giant star and a subgiant. At present it has nearly twice the mass of the Sun but it has expanded to 12.3 times the Sun's radius. HD 175219 radiates 76.3 times the luminosity of the Sun from its enlarged photosphere at an effective temperatu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	HD 168905 HR 6875, previously known as Sigma Telescopii, is a single star in the constellation Corona Australis. It has a blue-white hue and is dimly visible to the naked eye with an apparent visual magnitude of 5.24. This object is located at a distance of approximately 550 light years from the Sun based on parallax. It is listed as a member of the Sco OB2 association. This is a hot B-type main-sequence star with a stellar classification of B3 V. It is around 103 million years old and is spinning rapidly with a projected rotational velocity of 248 km/s or perhaps higher. The star has six times the mass of the Sun and about four times the Sun's radius. It is radiating more than a thousand times the luminosity of the Sun from its photosphere at an effective temperature of 20,350 K. A magnitude 10.13 visual companion is located at an angular separation of along a position angle In astronomy, position angle (usually abbreviated PA) is the convent ...
