Sirius B is according to the (U - B), (B - V) two-color diagram still on the main sequence and has an effective temperature of 24000 K. The same result is obtained frbm the (u-b), (b- y) diagram. The one named by earthlings as Sirius B is the isle named Osiris. Sirius B A diameter of approximately 11,800 km (7,300 miles). The Isle of Osiris has mountains and rolling hills with water. This star would give off similar brightness and radiation to Sirius A and, when it is closest to Sirius A would be a very strong 'second sun' for any planet near the outer rim of the goldilocks zone for Sirius A. In 2012 I had great difficulty to see the Pup, but now it was rather easy. The Bolometric Correction So how do we measure the bolometric magnitude of a star? The (B - V) color is surprisingly blue.
which to calculate using this website is too large. La couleur hexadécimale b0b5b6 a les valeurs RGB R:176, G:181, B:182 et les valeurs CMYK C:0.03, M:0.01, Y:0, K:0.29 Sirius B (the Pup) - posted in Sketching: Because seeing was good at Christmas I observed Sirius.

A little device as small as an external hard drive or a smartphone, but with the same power as a desktop PC. As a white dwarf star, Sirius B has a density 92 000 times our own sun.
Osiris has less humidity with some snow, one moon and 3 smaller planets. The Sun's Mass is 1,989,100,000,000,000,000,000 billion kg. It has a gravitational force that is about 350, 000 times stronger than Earth’s.
