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.
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.
