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.

What are the similarities and differences between sirius and sirius b stars?
Sirius, also known as Sirius A, is a main-sequence star and the brightest star in the night sky, while Sirius B is its companion, a white dwarf. Both stars are part of the same binary system and share a common origin, but they differ significantly in their characteristics; Sirius A is larger, hotter, and more luminous than Sirius B, which has exhausted its nuclear fuel and is much smaller and dimmer. Their orbital dynamics are also distinct, with Sirius B having a highly elliptical orbit around Sirius A. Overall, they illustrate the evolutionary stages of stars within a binary system.
What elements make up Sirius?
Sirius, the brightest star in the night sky, is a binary star system composed of two stars: Sirius A and Sirius B. Sirius A is a main-sequence star primarily made up of hydrogen and helium, with heavier elements like oxygen, carbon, and nitrogen present in smaller amounts. Sirius B, on the other hand, is a white dwarf that evolved from a red giant and is primarily composed of carbon and oxygen.
