Why Vega brighter than Arcturus?
The apparent brightness of stars depends on:* The distance * The actual brightness * In some cases, the brightness may be dimmed by clouds of dust and gas, between us and the distant star. In the case of Vega and Arcturus, Vega is NOT brighter than Arcturus. Their apparent magnitude (brightness) is about the same, with Arcturus perhaps being slightly brighter, depending on the source consulted. In terms of real brightness ("absolute magnitude"), Arcturus is actually brighter. When consulting numbers, please remember that smaller numbers refer to brighter objects.
Why Vega is brighter than Arcturus?
1. It might be closer to us, 2. it might be a bigger and brighter star. Arcturus is 35 light years away and has an absolute magnitude of -0.3, which makes it 100 times brighter than the Sun, while Vega is 26 light years away and has an absolute magnitude of 0.5, about half as bright as Arcturus. From Earth they are both about the same brightness.
Why is Vega brighter than Betelgeuse?
A star's brightness is a function of its luminosity, or the amount of energy it produces per unit time. Vega must have a higher luminosity, meaning it fuses more material than Betelgeuse in a given period of time.
What planet is occasional brighter then Jupiter?
Venus is occasionally brighter than jupiter
What planet is brighter than venus?
Venus, at its brightest, is brighter than any other planet. However, when it's not at its brightest, there are a couple of others than can be brighter if they're near their brightest, Mars and Jupiter being the most notable.
Why is the vega brighter than arcturus?
Arcturus is a bit brighter than Vega, actually.
Which star is brighter Vega or Betelgeuse?
Brightnest is a factor of luminousity and distance as seen from Earth. (Apparent magnitude)Vega - 0.03.Betelgeuse: 0.42So Betelgeuse is brighter as viewed from Earth.
Which is brighter Vega or Canopus?
Canopus is brighter than Vega. With an apparent magnitude of about -0.72, Canopus is the second-brightest star in the night sky, while Vega has an apparent magnitude of around 0.03. This difference in brightness makes Canopus significantly more luminous to the naked eye compared to Vega.

What is the difference between star Vega and star Capella?
Vega is brighter than Capella. Vega is closer to Earth than Capella. Vega is blue-white, Capella is yellow-ish. The name Vega comes from Arabic, whereas the name Capella comes from Latin. The meaning of Vega is a type of bird, the meaning of Capella is a type of mammal. :o)

From Earth they are both about the same brightness.
What is the color and size of the vega star?
Vega is a white star with an A-type spectrum. Its absolute magnitude (magnitude at a standard distance of 10 parsecs) is 0.5 making it 4 magnitudes brighter than the Sun, i.e. 40 times brighter. Its distance is 30 light years.
What is the color and size of of the star vega?
Vega is a white star with an A-type spectrum. Its absolute magnitude (magnitude at a standard distance of 10 parsecs) is 0.5 making it 4 magnitudes brighter than the Sun, i.e. 40 times brighter. Its distance is 30 light years.
Why is Vega brighter than Betelgeuse?
A star's brightness is a function of its luminosity, or the amount of energy it produces per unit time. Vega must have a higher luminosity, meaning it fuses more material than Betelgeuse in a given period of time.
Which is brighter the Sun or Vega?
Brightness is a function of a stars luminousity as seen from Earth. The Sun is far brighter than Vega. However, if they were both viewed from the same distance, then Vega would be brighter.
Is Vega or Betelgeuse the brightest star?
Brightness is a function of a stars luminosity as observed from Earth. So our Sun is the brightest. Vega has an apparent magnitude of: 0.03 Betelgeuse has an apparent magnitude of 0.42 So, in apparent magnitude, Vega is brighter.
Is green brighter than yellow?
