Talk:Distance modulus

Failed GA
I've removed this from the list of GA self nominations for a few reasons. The article is rather short, it's basically a definition and examples. All references are tangential, merely verifying that the examples given are factual. How did the concept of the distance modulus arise? How did it become standard?

In the case of the LMC, this means that the supernova SN1987A, with a peak apparent magnitude of 2.8, had an absolute magnitude of -15.7 - fairly low by supernova standards. &mdash; How the reader supposed to understand that this follows? More importantly, is it germane to the article?  Pagra shtak  00:12, 10 March 2006 (UTC)

Changing 'luminosity' to 'flux' or 'irradiance' in the inverse square law
As the luminosity of an object is an intrinsic property of it, it will not vary with distance to an observer. That is why it is confusing to state an inverse square law for luminosities. Instead, one should say that the flux or irradiance of the object adheres to the inverse square law, as the flux / irradiance *does* depend on the distance from which the source is observed. This is in accordance to Wikipedia's descriptions of luminosity and irradiance. (In astronomy, 'flux' is more common, although there does not seem to exist a page dedicated to flux in the astronomical sense.) — Preceding unsigned comment added by Martijn Oei (talk • contribs) 16:23, 3 October 2015 (UTC)

Relation to implied distance
If true, could we note somewhere that +5 on distance modulus implies 10 times further away ? Perhaps have a short table ? - Rod57 (talk) 19:25, 16 January 2017 (UTC)

Example of usage for galactic distances
gives a table of estimates of distance modulii for Andromeda galaxy, with the reddening values used. - Rod57 (talk) 19:40, 16 January 2017 (UTC)
