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.
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.
What is the radius of Arcturus compared to the Earth?
Arcturus has a radius about 26 times that of our Sun.Our Sun has a radius about 109 times that of Earth.So a quick bit of math: 109 x 26 = 2,834 times that of Earth
If Vega is 25.3 light year from earth and arcturus is 36.7 light years away which star would have a greater parallax explain?
Vega would have a greater parallax due to its closer distance to Earth compared to Arcturus. Parallax is the apparent shift in position of an object when viewed from different perspectives, and the nearer an object is to the observer, the larger its parallax.
