"There is a 100% chance you are exactly where you need to be right now... ~~~> Sirius (/ˈsɪri.əs/, a romanization of Greek Σείριος, Seirios, lit. "glowing" or "scorching") is a #starsystem and the brightest star in the Earth's night sky. With a visual apparent magnitude of −1.46, it is almost twice as bright as Canopus, the next brightest star. The system has the Bayer designation Alpha Canis Majoris (α CMa). What the naked eye perceives as a single #star is a binary star system, consisting of a white main-sequence star of spectral type A1V, termed Sirius A, and a faint white dwarf companion of #spectral type DA2, called Sirius B.
Sirius appears bright because of its #intrinsic luminosity and its proximity to #Earth. At a distance of 2.6 parsecs (8.6 ly), as determined by the Hipparcos astrometry satellite, the Sirius system is one of Earth's near neighbours. Sirius is gradually moving closer to the #SolarSystem, so it will slightly increase in brightness over the next 60,000 years.
Sirius A is about twice as massive as the #Sun and has an absolute visual magnitude of 1.42. It is 25 times more luminous than the Sun but has a significantly lower luminosity than other bright stars such as Canopus or Rigel. The system is between 200 and 300 million years old. It was originally composed of two bright bluish #stars. The more massive of these, Sirius B, consumed its resources and became a red giant before shedding its outer layers and collapsing into its current state as a white dwarf around 120 million years ago.
The heliacal rising of Sirius marked the flooding of the Nile in #AncientEgypt and the "dog days" of summer for the ancient Greeks, while to the Polynesians in the Southern Hemisphere the star marked winter and was an important reference for their navigation around the Pacific Ocean."
