Sirius A and B were never discovered. They have been in the night sky since humanoids first roamed the Earth. Even the dinosaurs would have seen Sirius.
So no one, or creature can be said to have "discovered" Sirius.
No, Sirius is not an asteroid. Sirius is a binary star system consisting of the brighter star, Sirius A, and its companion, Sirius B, which is a white dwarf star. It is the brightest star in the Earth's night sky.
Yes, Sirius is a binary star system composed of two stars, Sirius A and Sirius B. As of now, there have been no confirmed exoplanets detected in orbit around either star.
Sirius is the brightest star in the night sky of earth not a galaxy
Sirius has a lower absolute magnitude than Rigel. Sirius is one of the brightest stars in the sky with an absolute magnitude of 1.42, while Rigel has an absolute magnitude of -8.1, making it much brighter than Sirius.
Sirius is a binary star system consisting of two stars, Sirius A and Sirius B. Both stars have magnetic fields, but the specific properties of their magnetism are not well understood. It is known that magnetic fields play a role in the interaction between the two stars, but further research is needed to fully understand the magnetism of Sirius.
Look up the Wikipedia article, "Sirius", for more details. Briefly, it is: the brightest star in the sky (however, some planets, which also look like stars, are brighter); 8.6 light-years away; a double star; one of the components (Sirius B) was the first white dwarf to be discovered.
Sirius is Harry's godfather. Sirius Black is Harry's godfather.Harry is sirius's Godson.
It is not real. Sirius is a two-star system containing only Sirius A and Sirius B.
It can be argued that Harry did, because he SAW Sirius before getting on the Knight Bus. He didn't know then, however, that the dog he saw was Sirius. He just thought it was a dog. After he learned who Siruis Black was however, the first one to see Sirius was Ron. Peter Pettigrew, disguised as Ron's rat, Scabbers, led him into the Whomping Willow and then Harry and Hermione followed.
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).
No. Sirius consists of two stars. Sirius A is larger than the sun but is not a giant. Sirius B is a white dwarf,
No, but Sirius B is,
The Alan Parsons Project - Sirius
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 is actually a binary star system. Sirius A has an apparent magnitude of -1.46 whereas Sirius B has an apparent magnitude of 8.3
No, Sirius is not an asteroid. Sirius is a binary star system consisting of the brighter star, Sirius A, and its companion, Sirius B, which is a white dwarf star. It is the brightest star in the Earth's night sky.
The temperature of Sirius A is about 9,940K (or 9,666.85C).
