What is the name of the farthest and brightest star in the universe?
Every star has his own characteristics. In the clear night sky, thousands of stars can be seen by the naked eye. Together with countless faint stars, they form a fashionable brocade in the night sky. Stars come in different colors, sizes, shapes and ages. The most striking feature that distinguishes them is brightness. Astronomers use the system created by the Greek astronomer Hippocrates in 120 BC to measure the brightness of celestial bodies. Hipachas divided the brightness of the stars that can be seen on the earth into six levels. He classified the brightest stars he could see into the first category and the darkest stars into the sixth category. The magnitude adopts logarithmic law. Under this measurement law, a reduction of magnitude by one unit means that the apparent brightness is enhanced by 2.5 times. Here are the top ten brightest stars, which add endless elegance to the earth's night sky. Sirius is the brightest star in the night sky. Sirius's name comes from the Greek word "Sirius", which means "scorching heat". A star on Sirius Canis Canis, about 8.6 light-years from Earth. In ancient Greece, the rise of Sirius marked the hottest time in summer. This is also the origin of the phrase "dog days in midsummer". Second, the old star is a star in the constellation Carina, which is 650 light years away from the earth and the second brightest star in the sky. Carina is a part of the former Southern Constellation. The Southern Constellation is the ship on which Jason and Argo heroes are looking for golden fleece. The other two components of the Southern Constellation are the Sail Constellation and the Stern Constellation. Laonian will eventually become one of the largest white dwarfs in the Milky Way, and its mass may be large enough to burn its own carbon, thus becoming a rare neon-oxygen white dwarf. Third, the alpha binary Alpha binary is actually made up of three stars linked by gravity. The two main stars are Alpha A and Alpha B, and the smallest one is a red dwarf named Alpha C. Their average distance from the Earth is 4.3 light years, and they are the closest neighbors to the solar system in space. Arcturus and arcturus are the brightest stars in the night sky in the northern hemisphere. It is called "Bear Watcher", next to Ursa Major, near the North Pole. Arcturus's name comes from the Greek word "Arktos", which means "bear". Arcturus is the brightest star in the Mu Fu constellation, about 36 light years away from the Earth. Its mass is twice that of the sun, and its brightness is 265,438+05 times that of the sun. 5. Vega Vega's name comes from Arabic, meaning "swooping eagle" or "vulture". The brightest star in Vega Lyra. Lyra is small, but it is famous for belonging to the ring nebula. Vega is a hydrogen-burning dwarf, with brightness 54 times that of the sun and mass 1.5 times that of the sun. It is 25 light years away from the earth, which is quite close. Capella Capella is the main star of Auriga. It is the brightest star in this constellation, near the north celestial pole and about 46 light-years away from the earth. Capella is a fascinating binary star, consisting of a bright yellow giant star and a dim red dwarf star. Betelgeuse is the bright Betelgeuse on the heel on the west side of Orion. In ancient mythology, Betelgeuse was the place where Orion and Scorpio were bitten by Scorpio after fierce fighting. In Arabic, Betelgeuse means "feet" Betelgeuse is a bright binary star in Orion. Betelgeuse A is a blue Supergiant star whose light is 40,000 times that of the sun. Although it is 775 light years away from the earth, it still shines in the night sky. Eight, South River Three South River Three is located in the small dog constellation. Its volume is twice that of the sun and its brightness is seven times that of the sun. In winter in the northern hemisphere, you can easily find it in the east of Orion. Nine, Achena Star The name of Achena Star comes from Arabic, meaning "the end of the river". This name suits it very well, because it is located at the southernmost tip of Apollo River constellation. Aquinas is the hottest of the ten brightest stars. Its temperature is as high as 24740 to 33740 degrees Fahrenheit (absolute temperature 14000- 19000). Its luminosity is 2900 to 5400 times that of the sun, and it is 1 14 light years away from the earth. Betelgeuse is 55,000 times brighter than the sun, but the distance of 430 light years makes it the last of the top ten brightest stars. Betelgeuse's name comes from Arabic, which means "armpit". Betelgeuse is a red Supergiant star with a diameter of 650 times that of the sun and a mass of 15 times that of the sun. Betelgeuse is a very old star, which is nearing the end of its life.
