Because Rigel is much farther away. Rigel is 770 light-years away, and Sirius is only 8.6 light-years away.
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.
No, which means that Rigel appears brighter.
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.
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.
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, which means that Rigel is brighter.
Rigel is approximately ten times LARGER than Sirius

No, which means that Rigel appears brighter.
Without knowing direction of even hemisphere, it's difficult to be precise. A best guess would be Sirius or Rigel.
No because they might just be bright because they are close, like Sirius and Procyon, or they might be bright because they are really are huge stars a long way way, like Rigel and Deneb.
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.
