Sirius B is a white dwarf, meaning it is already the remnant of a dead star. That star died about 120 million years ago.
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.
No, but Sirius B is,
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).
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.
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

Intrinsically Aldebaran is brighter than Sirius B which is a white dwarf star, no longer generating new heat.

Sirius is a binary star. Sirius A has a temperature of about 10,000 K Sirius B has a temperature of about 25,200 K 9,940(a) k 25,200 (b) k 78
It is not real. Sirius is a two-star system containing only Sirius A and Sirius B.
Sirius B is a white dwarf. As the name suggests, it will appear white.
Sure - the two attract each other. In the case of a double star - as Sirius A and Sirius B - both revolve around their common center of mass.

No. Sirius consists of two stars. Sirius A is larger than the sun but is not a giant. Sirius B is a white dwarf,
Neither Sirius A nor Sirius B have any known planets.
