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 system and does not have a surface temperature that can be measured in Celsius. The primary star, Sirius A, has a surface temperature of about 9,900°C (17,800°F), while the secondary star, Sirius B, is a white dwarf with a surface temperature of around 25,000°C (45,000°F).
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?

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.
What can you infer about Sirius's size and temperature that would explain why it look's brighter than Barnard's Star?
Sirius is bigger and hotter than Barnard's Star, which makes it appear brighter. The larger size of Sirius means it has a greater surface area emitting light. Additionally, its higher temperature causes it to emit more light energy compared to Barnard's Star.
The temperature of a star is actually the temperature of what?
the surface of the star.
What is the surface temperature of the Acamar star?
The surface temperature of the Acamar star is approximately 8,500 Kelvin.
