Yes it is much bigger.Probably 5 suns can fit in sirius.Not only is sirius bigger but it is much hotter as well.
In terms of absolute magnitude, yes. Sirius is a brighter star than the sun.
The sun only appears brighter than Sirius because it much closer, by a factor of about half a million. In reality, Sirius is about 25 times brighter than the sun.
No. The sun is the closest star to Earth by several orders of magnitude. It is roughly half a million times closer to us than Sirius.
Sirius is actually two stars; a white main sequence star (Sirius A) and a white dwarf (Sirius B) both of which are hotter than the sun.
how much hotter is Sirius vs the sun
The brightest OBJECTS in the sky, after the Sun, are the Moon, followed by planets Venus, Jupiter, and Mars (on rare occasions, Mars is brighter then Jupiter), followed by the star Sirius.The brightest stars proper are Sirius, followed by Canopus, Toliman, Arcturus, Vega...
The brightest star in the sky, is our Sun. It is a star. After the Sun, Sirius is the next brightest star, or the brightest in the night sky.
Rigel is approximately ten times LARGER than Sirius
Sirius is a star therfore is doesnt orbit. Furthermore sirius is to distant for us to obtain such information.
Not necessarily. They can be brighter, or less bright. Both the energy saving light bulbs and the old-fasioned incandescent light bulbs come in different powers.
The sun appears brighter than Sirius does because it is about half a million times closer to us.
It is closer to us.
Venus has an apparent magnitude [See related link] of -3.82 when it is opposite from the Sun, whereas Sirius has an apparent magnitude of -1.47. So Venus is always brighter (When seen) than Sirius.
I'm not too sure what other people think. I know that the Sun shines brighter than Sirius.
While Pollux is actually brighter than Sirius, Sirius appears brighter because it is several times closer.
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.
From Earth, the brightest star other than the Sun is Sirius. Jupiter and Mars are always brighter than Sirius, and Venus and Mercury can be.
Sirius has a luminosity of: 25.4 while Rigel has a luminosity of: 66,000 Making Rigel brighter than Sirius.
No. There is no such thing as an "earth-like star" as Earth is a planet, not a star. Sirius A is a star that is larger and brighter than the sun.
Sirius is about 25 times as bright as our Sun. That refers to the absolute magnitude; of course, our Sun looks much brighter to us, because it is closer.
Sirius has less absolute magnitude than Rigel. Sirius is smaller and less luminous than Rigel, but much closer to us, so Sirius appears brighter. Sirius, in fact, is the brightest star in our sky (with the exception of our own star, the sun.) Rigel is still pretty bright, but many times farther away from us than Sirius.
Yes
