It is the brightest star in Centaurus constellation and the third brightest star in sky. At the other end of the constellation is the second brightest star The location of the main sequence star in the night sky is determined by the Right Ascension (R.A.) and Declination (Dec.), these are equivalent to the Longitude and Latitude on the Earth. It is located at the southern end of its constellation and therefore is not visible by a lot of northern hemispheric countries. The Radial Velocity, that is the speed at which the star is moving away/towards the Sun is 18.60000 km/s with an error of about 3.00 km/s .
The number of A.U. The star's Galacto-Centric Distance is 7,392.00 Parsecs or 24,109.99 Light Years. You will receive a verification email shortly.There was a problem. The two stars, Achernar A (seven times the mass of the sun) and Achernar B (which is smaller), rotate about 6.7 Earth-sun distances or astronomical units apart.Achernar's apparent magnitude — how bright it appears to us — is 0.46. If you want that in miles, it is about 845,405,114,917,534.95, based on 1 Ly = 5,878,625,373,183.61 miles.In 2007, Hipparcos data was revised with a new parallax of 23.39000 which put Achernar at a distance of 139.45 light years or 42.75 parsecs. In the case of a star, its the galactic centre.
At the pole, the temperature may be above 20,000 K, while the equator is at or below 10,000 K. The average temperature of the star is about 15,000 K. The high polar temperatures are generating a fast polar wind that is ejecting matter from the star, creating a polar envelope of hot gas and plasma. which to calculate using this website is too large. Future US, Inc. 11 West 42nd Street, 15th Floor, This is very appropriate since Achernar is part of the constellation Eridanus, the river.
The source of the information if it has a Hip I.D. Achernar is a blue-white star 139 light years from Earth, it rotates very rapidly, and therefore is oval, and has a sister, Achernar B, and they both orbit at a distance of only 12 AU.. She is the least spherical star in the Milky Way, so she became the leader of the Oval Stars Community.. It is located at a distance of 310 light years from Earth. Achernar is a bright, binary star system in the constellation Eridanus, and is the ninth-brightest star in Earth's night sky. has done some calculations as to how long it will take going at differing speeds. Based on the star's spectral type of B3Vp , Achernar's colour and type is blue main sequence star. As the Earth orbits the Sun during this period, the observer (taking measurements at the opposite sides of the Earth's orbit) notices an apparent movement of the star compared to more distant stars. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days). "The effect can't be reproduced by common models of stellar interiors unless certain phenomena are incorporated, e.g., meridional circulation on the surface ("north-south streams") and non-uniform rotation at different depths inside the star. The time it will take to travel to this star is dependent on how fast you are going. It … Alpha Centauri is the nearest star system to the Sun, located at a distance of only 4.37 light years or 1.34 parsecs from Earth. Achernar's location is:"The high degree of flattening measured for Achernar — a first in observational astrophysics — now poses an unprecedented challenge for theoretical astrophysics," he wrote. Achernar (Alpha Eridani) is the most luminous star in the constellation Eridanus, marking the southern termination of the River, and is the 9th most luminous star in the entire night sky.
Comments may be merged or altered slightly such as if an email address is given in the main body of the comment.You can decline to give a name which if that is the case, the comment will be attributed to a random star. Its variable/pulsating period lasts for 0.1 days (variability). Alpha Centauri is only slightly brighter than Arcturus in Boötes constellation and Vega in Lyra.
Stellar Parallax. Alpha Centauri is the nearest star system to the Sun, located at a distance of only 4.37 light years or 1.34 parsecs from Earth.
It is the brightest star in Centaurus constellation and the third brightest star in sky. [See our facts about ~.]
