Does Rigel have greater apparent magnitude than Sirius?
No, which means that Rigel appears brighter.
How many times brighter is Capella than the sun?
Rigel has a luminosity of 66,000 times greater than our Sun.However, in apparent magnitude (Brightness) it has a magnitude of 0.18 whereas the Sun is -26.73.
How many times larger is Betelgeuse in terms of diameter than Rigel?
Betelgeuse is around 10 times greater in diameter than Rigel.
Even though this star has an absolute magnitude greater then that of sirius it looks dimmer from earth since it's 100 times farther away?
The apparent brightness of a star depends mainly on (1) its absolute (i.e., real) brightness, and (2) the square of its distance from us. The absolute magnitude of Sirius is +1.45, while that of Rigel is -6.95, meaning that Rigel is approximately 2,290 times as bright as Sirius. However, Rigel is approximately 100 times as far from us (870 light years versus 8.6 light years), which reduces its brightness relative to Sirius by a factor of over 10,000. This makes Sirius about 4.5 times brighter than Rigel for a difference of 1.62 magnitudes (-1.44 relative magnitude for Sirius versus +0.18 for Rigel).
Is rigel smaller than deneb?
Yes, Rigel is smaller than Deneb.
Does Rigel have greater apparent magnitude than Sirius?
No, which means that Rigel appears brighter.

Why is Rigel appears brighter than aldeberan even though aldeberan is technically brighter than Rigel?
The absolute magnitude of Rigel is -7.92 while that of Aldebaran is -6.41. This means that Rigel is approx 4 times brighter than Aldebaran - technically. So the question is based on a flawed grasp of absolute magnitude.
Even though this star has an absolute magnitude greater than that of sirius it looks dimmer from earth since its 100 times farther away?
Rigel has a greater absolute magnitude than Sirius but apears dimmer from Earth do to the farther distance the light waves must travel through space (just a little more information : ), but there are probably alot more stars around that distance
Which star has the less absolute magnitude rigel or Sirius?
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.
What is a scalar magnitude?
Magnitude means size. The magnitude of 8 is greater than the magnitude of 4. The magnitude of 1023209138109283 is greater than the magnitude of 12. =)) .... enjoyy... =D
How many times larger is Betelgeuse in terms of diameter than Rigel?
Betelgeuse is around 10 times greater in diameter than Rigel.
Vector component greater than the vectors magnitude?
can a vector have a component greater than the vector magnitude
Can a vector have a component greater than the magnitude of vector?
no a vector cannot have a component greater than the magnitude of vector
When is the magnitude of the sum of vectors A+B greater than that of A-BWhen is the magnitude of A-B greater than that of A+B?
none

No.
