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.
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.
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.
How many times brighter is the galaxy IRAS than the sun?
300,000,000,000,000 times brighter than the sun
Why is the vega brighter than arcturus?
Arcturus is a bit brighter than Vega, actually.

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 vega brighter than arthuros?
Vega appears brighter than Arcturus in the night sky because it is closer to Earth, being only about 25 light-years away compared to Arcturus which is around 37 light-years away. Additionally, Vega is a hotter and more luminous star compared to Arcturus, contributing to its perceived brightness.
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.
What is the distance from the sun to the star vega?
The distance from the sun to the star Vega is roughly 25.3 light years.
When was The Sun Shines Brighter created?
The Sun Shines Brighter was created in 2005.
How do you use the word brighter in a sentence?
Tomorrow is going to be a BRIGHTER day. The sun is BRIGHTER today then yesterday. Some day I will shine BRIGHTER than the sun.
