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 ...
Some are of the opinion that the apparent magnitude of Sirius is partly due to the whiteness of its tint and its greater intrinsic brilliancy; and that the red stars, Aldebaran, Betelgeuze, and others, would appear much brighter than now if of the same color as Sirius; rays of red light...
Sirius B is estimated at being 0.228 billion years old but could be between 0.2180 and 0.2380 Magnitude A number represents a star’s magnitude, whether apparent/visual or absolute. The smaller the number, the brighter the star is. The Sun is the brightest star and has the lowest of all ...
Located in theconstellationof Canis Major, Sirius shines with anapparent magnitudeof -1.46. It's noticeably brighter than its nearest rivalCanopus (α Car mag. -0.72)and four times more brilliant thanArcturus, the brightest star in the northern section of sky. Sirius is also known as the "Do...
8.6 light-years away, Sirius is practically an astronomical stone’s throw away. There are a few stars that are closer to us, including the familiar Alpha Centauri system and a handful of red dwarfs, but none of them are a match for Sirius’s absolute magnitude and that makes the ...
