Flughafentransfer in Rigel

Rigel ist ein blauer Überriesenstern im Sternbild Orion. Er trägt die Bayer-Bezeichnung β Orionis, was latinisiert wird zu Beta Orionis und abgekürzt Beta Ori oder β Ori. Rigel is the brightest and most gigantic component – and the eponym – of a star system of at least four stars that appear as a single blue-white reduction of lighthearted to the naked eye. This system is located at a disaffect of approximately 860 light-years (260 pc) from the Sun.

A star of spectral type B8Ia, Rigel is calculated to be anywhere from 61,500 to 363,000 times as vivid as the Sun, and 18 to 24 epoch as massive, depending on the method and assumptions used. Its radius is exceeding seventy time that of the Sun, and its surface temperature is 12.100 K. Due to its stellar wind, Rigel’s mass-loss is estimated to be ten million times that of the Sun. With an estimated age of seven to nine million years, Rigel has exhausted its core hydrogen fuel, expanded, and cooled to become a supergiant. It is received to halt its cartoon as a type II supernova, leaving a neutron star or a black hole as a unchangeable remnant, depending on the initial enlargement of the star.

Rigel varies slightly in brightness, its apparent magnitude ranging from 0.05 to 0.18. It is classified as an Alpha Cygni modifiable due to the amplitude and periodicity of its brightness variation, as with ease as its spectral type. Its intrinsic variability is caused by pulsations in its unstable atmosphere. Rigel is generally the seventh-brightest star in the night proclaim and the brightest star in Orion, though it is occasionally outshone by Betelgeuse, which varies greater than a larger range.

A triple-star system is estranged from Rigel by an angle of 9,5 Bogensekunden. It has an apparent magnitude of 6.7, making it 1/400th as talented as Rigel. Two stars in the system can be seen by large telescopes, and the brighter of the two is a spectroscopic binary. These three stars are all blue-white main-sequence stars, each three to four epoch as terrible as the Sun. Rigel and the triple system orbit a common center of gravity like a mature estimated to be 24,000 years. The inner stars of the triple system orbit each other all 10 days, and the outer star orbits the inner pair every 63 years. A much fainter star, separated from Rigel and the others by nearly an arc minute, may be share of the thesame star system.
