Previous problems show that Absolute Magnitude (M) is determined by the Apparent Magnitude (m) and the distance of the star (d). This can be written as ... M= m+5-5 log₁0 (d) By reformulating the problem you can also find the distance of a star if M and m are known. Recall that the reason for the difference between m and M of a star is the distance to the star. The greater the distance between the star's actual distance and the standard distance of 10pc, the greater will be the difference between magnitudes. In fact, the quantity (m-M) is called the distance modules. Use the table provided to answer the following questions. 7. What is the distance to a star having m=+5 and M = -5? 8. What is the distance to a star having m=+1 and M = -6? 9. What is the distance to a star having m = +14 and M = -1?
