[QUOTE="collinsmark, post: 6170144, member: 114325"] Hello [USER=657264]@James Beedy[/USER], Ya' know, you can easily google "distance modulus of a star" and you'll get detailed explanations in the first few hits. It's not hard to find. Per PF rules, you must show that you've put at least some effort into solving the problem. -------------- (At the risk of offering too much help -- again, a quick google search will give you all of this) If we define our terms as: [itex] m: [/itex] apparent magnitude of the object [itex] M: [/itex] absolute magnitude of the object [itex] \mu: [/itex] distance modulus [itex] d: [/itex] distance, in units of parsecs then the distance modulus is [itex] \mu = m - M [/itex], and is related to the distance by the following formula, [itex] m - M = 5 \log_{10} d - 5 [/itex] [/QUOTE]
