How long will the star Sirius live?

Estimates are that this star is about 200 to 300 million years old. There is a rule of thumb for lifetime of a star: 2x the mass, 1/10th the life. Our sun is expected to live at least 10 billion years total. That puts Sirius at a total life of 1 billion years.

Is Sirius the South star?

Believe it or not, the brightest star in the sky – our sparkling night beacon, Sirius in the constellation Canis Major the Greater Dog – will someday serve as a very reasonable, and certainly very noticeable, South Star. Unlike the Northern Hemisphere, the Southern Hemisphere currently doesn’t have a bright pole star.

Who was the first person to see Sirius?

That Sirius is a binary star was first reported by the German astronomer Friedrich Wilhelm Bessel in 1844. He had observed that the bright star was pursuing a slightly wavy course among its neighbours in the sky and concluded that it had a companion star, with which it revolved in a period of about 50 years.

Where does Sirius appear in the night sky?

As it happens, this constellation (an officially named group of stars that appear close together in the sky from Earth) is in an especially “busy” part of the sky – a regular ​ tour de force ​ for serious stargazers. So finding Sirius, along with the host of alluring astronomical attractions in the celestial neighborhood, is actually pretty easy.

What kind of star is the Sirius Star?

It’s a main-sequence star, meaning it produces most of its energy by converting hydrogen into helium through nuclear fusion. Sirius has a small, faint companion star appropriately called the Pup. That name signifies youth, but in fact the companion to Sirius is a dead star called a white dwarf.

How big is Sirius compared to the Sun?

It is a binary star in the constellation Canis Major. The bright component of the binary is a blue-white star 25.4 times as luminous as the Sun. It has a radius 1.71 times that of the Sun and a surface temperature of 9,940 kelvins (K), which is more than 4,000 K higher than that of the Sun.
