What would happen if the sun was replaced by Sirius A?

Sirius A is about twice as massive as our sun, but has a surface temperature of around 10000 degrees Kelvin, compared with our suns surface temperature of around 5800 Kelvin. The Earth and all of the other planets would be a lot hotter if they remained at their current orbit, though the orbits would change as the gravitational pull of Sirius A would be greater. The water on earth would boil off and it would become a barren planet that could not support life. Even Mars may be too hot to support life if Sirius A were our star.


When is the sirius B star going to burn out?

It already has. Sirius B is a white dwarf, the dense remnant of a dead star. While it is no longer producing energy through fusion, Sirius B still glows with the leftover heat of when it was an active star. Because of the huge amount of heat and relatively small surface area, it will take trillions of years for Sirius B to cool.


How far apart are 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).


Is sirius a cold?

No. Sirius is far from a cold star. Sirius is actually a binary system about 8.6 light years away. Sirius A is a white main sequence star just over twice the size of the sun. Sirius B is a white dwarf stellar remnant of about 0.978 solar masses. The temperature of the two stars are far higher than that of our sun. The sun is about 5778 Kelvin, Sirius A is almost twice that at 9,940 K and Sirius B is many times that at 25,200 K.


Is Sirius A a cold star?

No. There is no such thing a a cold star. Sirius consists of two stars, both of which are hotter than the average star.

What is the flickering star in the eastern sky tonight?

The flickering star in the eastern sky tonight is most likely Sirius, also known as the Dog Star. It is the brightest star in the night sky and is visible in the early evening in the eastern sky. Sirius is a binary star system, meaning that it is made up of two stars that orbit each other. The main star, Sirius A, is a white-hot star that is much brighter than our Sun. The companion star, Sirius B, is a white dwarf star that is much fainter than Sirius A. Sirius is a very hot star, with a surface temperature of over 10,000 degrees Celsius. This heat causes the star to emit a lot of light, which is why it is so bright. Sirius is also very large, with a diameter that is about twice the diameter of our Sun. Sirius is a relatively young star, with an age of only about 250 million years. This means that it is still burning hydrogen fuel in its core. Once Sirius runs out of hydrogen fuel, it will eventually become a red giant star. Sirius is a beautiful and fascinating star that is sure to amaze stargazers for years to come.
