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 celsius temperature of Sirius?
Sirius is a binary star. The temperature of Sirius A is roughly 10,000 degrees and Sirius B is about 25,200 degrees. These are only rough estimates as it is extremely hard to measure the exact temperature of something so hot
What is Sirius Surface temperature?
The surface temperature of Sirius A, the primary star in the Sirius binary system, is estimated to be around 9,940°C (17,984°F). Sirius B, its white dwarf companion, is much hotter with a surface temperature of about 25,000°C (45,000°F).
How hot is Sirius?
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).

What is the surface temp and color of the siruis?
Sirius has a surface temperature of approx 9940 K, and is a white main sequence star.
What is the Surface temperature of Sarin the Star?
Sarin, the star, is not a widely recognized celestial body. If you meant "Sirius," which is often referred to as "the Dog Star," its surface temperature is approximately 9,940 K (Kelvin). This high temperature makes Sirius one of the hottest stars visible to the naked eye. If you were referring to a different star, please clarify for more accurate information.
What star has a surface temperature 9000k and luminosity about 1 to 20 times greater than the sun?
Sirius
What star Is close to 10000 degrees?
The star closest to 10,000 degrees Celsius is typically considered to be Sirius B, the white dwarf companion of Sirius A. Sirius B has a surface temperature of about 25,000 degrees Fahrenheit (approximately 14,000 degrees Celsius), while Sirius A, the brighter of the two, has a surface temperature around 9,940 degrees Fahrenheit (about 5,500 degrees Celsius). Other hot stars, such as some O-type and B-type stars, can also reach temperatures near that range.
How hot is the core of Sirius?
Sirius is hotter than the sun. -------------------------------------- The temperature at the surface of Sirius is estimated to be 9 440 K. The temperature at the surface of Sun is estimated to be 5 778 K.
