Rigel is approximately ten times LARGER than Sirius
Yes it is much bigger.Probably 5 suns can fit in sirius.Not only is sirius bigger but it is much hotter as well.
Sirius is a star therfore is doesnt orbit. Furthermore sirius is to distant for us to obtain such information.
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.
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...
About 8.6 light-years or 8.6 yrs x 365 days/1 yr=3139 days * 24 hr/1day=75,336 hrs *60 secs/1hr=4520160 secs * c (speed of light 186,000 miles/sec)=84,749,760,000,000 miles from Earth.......(or how much our country with be in debt by 2020 LOL )
Sirius, which means that Rigel is brighter.
Well, honey, Sirius takes the crown for being the brightest star in the night sky, shining like a diamond in the rough. Rigel may be a hotshot in its own right, but it can't outshine the sass and sparkle of Sirius. So, if you're looking for some celestial bling, Sirius is the way to go.
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.
No, Sirius is the brightest star in the night sky. Rigel is one of the brightest stars in the constellation of Orion.
yes it is
I'm not sure exactly what detail you want, but here's a start. Rigel is a triple star system. The main star of the three is a very luminous star. It is a blue supergiant star.
I don't think that either of these stars "have" a black hole.
Despite being more intrinsically luminous than Sirius, Rigel appears dimmer in the sky due to its greater distance from Earth compared to Sirius. The brightness of a star as seen from Earth is influenced by both its intrinsic luminosity and its distance from us.
Yes, Rigel has a greater magnitude than Sirius. Rigel has an apparent magnitude of around 0.12, making it one of the brightest stars in the night sky, while Sirius has an apparent magnitude of about -1.46, making it the brightest star in the night sky.
No, which means that Rigel appears brighter.
Yes, Sirius is quite big while Barnard's star is small.
Yes, the star with the higher absolute magnitude will appear dimmer from Earth if it is located farther away. This is because brightness decreases with distance due to the inverse square law of light, meaning that a star will appear dimmer the farther it is from the observer.
