No, but Sirius B is,
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).
Where is Sirius b located in the night sky?
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.
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.
What is the absolute and apparent magnitude of Sirius B?
Sirius B is a faint white dwarf companion of Sirius A It has an apparent magnitude of +8.3 and an absolute magnitude of +11.18

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.
What color is Sirius B?
Sirius B is a white dwarf. As the name suggests, it will appear white.

What star is hotter but less luminous than Polaris?
The star that is hotter but less luminous than Polaris is Sirius B. While Sirius B has a surface temperature of around 25,000 K, significantly hotter than Polaris's approximately 6,000 K, it is a white dwarf and has much lower luminosity. Polaris, a supergiant star, shines brightly despite its cooler temperature due to its large size. Thus, Sirius B exemplifies the relationship between temperature and luminosity in stars.
