... Answer: Quoting from page 355, “Apparent brightness decreases inversely with the square of the distance...” So, the ratio of the distances is 1/5, the the apparent brightness ratio is 52 = 25. The closer star looks 25 times as bright. 23. What is a radial velocity curve? What kinds of stellar system ...
