200-300 million years old
Sirius, which means that Rigel is brighter.
Sirius is actually a binary star system.Sirius A is a type A1V star so has a colour of Blue White -> BlueSirius B is a white dwarf.
Sirius is a binary star system with two main stars, Sirius A and Sirius B. Sirius A, the brighter and more massive star, has a surface temperature of around 9,940°C (17,964°F). Sirius B, the smaller and fainter star, has a surface temperature of about 25,200°C (45,332°F).
Sirius is a star (actually, a binary star), so none, as stars do not have moons. Either or both of the stars that comprise Sirius could theoretically have planets which have moons, but if so, we don't know about them yet.
Sirius is a binary star. Sirius A has a temperature of about 10,000 K Sirius B has a temperature of about 25,200 K 9,940(a) k 25,200 (b) k 78
From Wikipedia: "The age of the system [Sirius is a double star] is estimated at around 230 million years." So, a fairly young star, at least if compared to typical stars, including our own Sun.

Sirius, the brightest star in the night sky, is a binary star system consisting of Sirius A and Sirius B. Sirius A, a main-sequence star, has a life expectancy of about 10 to 20 million years, while Sirius B, a white dwarf, represents the remnant of a more massive star that has already undergone its life cycle. The combined lifespan of the Sirius system reflects the evolution of its components, with Sirius A being relatively young at around 200 million years old.
No, because they are not. Sirius A and B are just two stars in a Galaxy of many billions of stars. Sirius is a few hundred million years old, younger than most of the stars in the Milky Way.
Sirius is Harry's godfather. Sirius Black is Harry's godfather.Harry is sirius's Godson.
It is not real. Sirius is a two-star system containing only Sirius A and Sirius B.
Sirius is a binary star system Sirius A and Sirius B.The distance separating Sirius A from B varies between 8.1 and 31.5 AU. (See related question).
It's very difficult to age individual stars, but it is estimated that the Sirius system is about 200 - 300 million years old. Sirius B became a white dwarf about 120 million years ago. Big stars like Sirius rarely last more than half a quarter billion years.
No. Sirius consists of two stars. Sirius A is larger than the sun but is not a giant. Sirius B is a white dwarf,
No, but Sirius B is,
The Alan Parsons Project - Sirius
Sirius, which consists of both Sirius A and Sirius B is in the constellation Canis Major, which, if you are looking south, appears below and to the left of Orion. Sirius B itself is too dim to be seen from Earth; the vast majority of the light from Sirius is from Sirius A. Even then, as a binary system, the two stars are too close together for us to see them separately.
