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.
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 star would have a greater parallax vega or arcturus?
Vega would have a greater parallax than Arcturus. Vega is closer to Earth at a distance of about 25 light-years, while Arcturus is approximately 37 light-years away. Since parallax measures the apparent shift of a star against distant background stars due to Earth's orbit around the Sun, closer stars exhibit larger parallax angles. Therefore, Vega, being closer, will show a more significant parallax shift than Arcturus.
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 size and apparent brightness of arcturus and vega?
