The Orbit of Sirius A and B . Sirius B is a DA2 dwarf star based on the spectral type that was recorded in Simbad at Strasbourg University. The period of the orbit is very close to 50 years. Sirius B, a white dwarf, is very faint because of its tiny size, only 12,000 kilometres in diameter. What the naked eye perceives as a single star is actually a binary star system, consisting of a white main sequence star of spectral type A1V, termed Sirius A, and a faint white dwarf companion of spectral type DA2, termed Sirius B. Sirius B is not part of the Canis Major constellation outline but is within the borders of the constellation. The star is a stronger source of X-ray radiation than Sirius A.

This blue, dwarf star has been called Sirius B, nicknamed The Pup. This image shows two sources and a spike-like pattern due to the support structure for the transmission grating. The dim source at the position of Sirius A – a normal star more than twice as massive as the Sun – may be due to ultraviolet radiation from Sirius A leaking through the filter on the detector.

Given the mass of the white dwarf and the 250 million year age of the system, Sirius B may once have been a hot class B3-B5 star that could have contained as much as 5 to 7 solar masses, the star perhaps losing over 80 percent of itself back into interstellar space through earlier winds. Sirius A. Sirius A is about twice as massive as the Sun and has an absolute magnitude of 1.42. The Sirius AB binary system has masses that are well determined from many decades of astrometric measurements. Sirius B in the highest dimension (24th) acts as a Cosmic Outpost for multiple federation bases in the Interdimensional Free Worlds Systems. Sirius is a binary star consisting of a main-sequence star of spectral type A0 or A1, termed Sirius A, and a faint white dwarf companion named Sirius B, which is a spectral type DA2 star. Sirius B became a white dwarf about 120 million years ago. Sirius B is a Dwarf Star type star. White dwarfs are the leftover remnants of stars similar to our Sun.
