(Celestial Objects) the brightest star in the sky after the sun, lying in the constellation Canis Major. It is a binary star whose companion,Sirius B, is a very faint white dwarf. Distance: 8.6 light years. Also called:the Dog Star,CaniculaorSothis ...
Sirius’ brightness can be attributed to its luminosity and proximity at a distance of 8.6 light-years. There are few stars that are closer to Earth, but none of them can match Sirius’ magnitude. Based on calculations from theEuropean Space Agency’s Hipparcos satellite, Sirius will continue ...
Sirius appears bright because of both its intrinsic luminosity and its proximity to Earth. At a distance of 2.6 parsecs (the Sirius system is one of Earth's near neighbors. Sirius A is about twice as massive as the Sun and has an absolute visual magnitude of 1.42. It is 25 times more ...

Its reappearance was observed from the same place in the autumn of 1896 at a distance of 3″.7, with a position angle of 195°. It has a period of 51½ years, and an orbit whose diameter is between those of Uranus and Neptune; its mass being one third that of Sirius and equal ...
Spectral observations are best obtained when the stars are at maximum distance, and redshifts which affirm the theory of relativity have been detected. Copernicus satellite observations have also revealed the emissions of UV and X rays from the dwarf. It is noted that Grecian records over 2000 ...
