Is Sirius a cold star?
No. Sirius is far from a cold star. Sirius is actually a binary system about 8.6 light years away. Sirius A is a white main sequence star just over twice the size of the sun. Sirius B is a white dwarf stellar remnant of about 0.978 solar masses. The temperature of the two stars are far higher than that of our sun. The sun is about 5778 Kelvin, Sirius A is almost twice that at 9,940 K and Sirius B is many times that at 25,200 K.
What star is the brigtest of all-stars the sun or the sirius star?
Neither. The Sun only appears bright because it is close. Sirius is far larger and brighter than our Sun. Our Sun is probably in the top 40% of all stars in the Milky Way, while Sirius is probably in the top 5%. But there are many other stars that are far brighter even that Sirius.
How is Sirius star different from all the other objects in the solar system?
Sirius is not part of our Solar System, so it is not appropriate to talk about "other objects in the solar system".
How much would you weigh on Sirius A?
If you weighed 100lb on Earth you would weigh about 5,400 lb for about a millisecond before you were incinerated and turned into vapour. Sirius A is a star about twice the size of our Sun.
Is Sirius A a main sequence star?
Polaris - the current North star is a multiple star system., consisting of the main star and smaller companions. The main star Alpha Ursae Minoris is a bright star, a 6 solar mass supergiant and it is a main sequence star. Orbiting very close to this main star is a white dwarf of roughly 1.5 solar masses. This is not a main sequence star. Orbiting further out is the third companion, a 1.39 solar mass star. This is a main sequence star. There are also two more distant components (α UMi C and α UMi D) - Polaris is thought to be part of an open cluster - I do not know if these later two stars are main sequence or not.
Is sirus an asteroid?
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.

Is the Sirius star extremely hot?

What is the shinyest star?

Is 'Sirius C' real or not?
It is not real. Sirius is a two-star system containing only Sirius A and Sirius B.
Is Sirius the largest star?
No. Sirius is the brightest star in Earth's night sky, but how bright a star appears is a product of its actual brightness and its distance from us. Sirius itself is actually two stars with Sirius A emitting the vast majority of the system's light. Sirius A is a fairly large star, but others are much larger.
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. Together, these elements contribute to the unique characteristics and luminosity of the Sirius system.
Is Sirius also called the North Star?
No, Sirius is not the North Star. The North Star, also known as Polaris, is located closest to the north celestial pole and serves as a guide for navigational purposes. Sirius is the brightest star in the night sky and is part of the constellation Canis Major.
