The artists renditon is very good and should be kept, but more astronomy pictures and graphs should be added to the article.

Basic infobox added
I've added a basic infobox for this star, however, among the missing information would be the stellar classification. I couldn't find any reliable information on this, and perhaps it's still unknown. I could also not find any boundaries for the approximation of its distance. &mdash; Northgrove 11:10, 20 February 2008 (UTC)

Discrepancy?
"HE 1523-0901 is the designation given to a red giant star," but, later in the article, we see that it's "approximately eight-tenths the size of the Sun."

A red giant that's only 1,000,000 km wide? No star so small would be visible 7,500 ly away. 68Kustom (talk) 07:10, 18 February 2009 (UTC)

That should really say 0.8 Solar masses. The star is a highly evolved red giant, giving it a much larger radius than the Sun and hence making it possible to see. --114.76.62.26 (talk) 10:21, 14 June 2009 (UTC)

Mass and size are two very different things, hence the confusion.

Also the article doesn't say 7,500 light years, it says 750 light years.

"Second" oldest?
On 22 Dec, 109.242.25.81 (talk) changed "This makes it the oldest object yet discovered in the galaxy," to "This makes it the second oldest object yet discovered in the galaxy,". I can find no supporting statement in the citation. Can anyone clarify what makes this the second oldest, or should we edit it back? --50.41.5.211 (talk) 15:25, 22 February 2013 (UTC)
 * I agree, and have reverted the change. HenryFlower 05:04, 14 March 2013 (UTC)
 * Was this maybe in reference to HD 140283? I got here in search of "the oldest known star", and found the information on this page a bit confusing when taking Methuselah into account. 98.194.174.9 (talk) 06:44, 2 August 2013 (UTC)


 * HD 140283 does beat it; I suppose you can call 1523-0901 the "oldest member of the galaxy", since HD 140283 is just passing through. — Preceding unsigned comment added by 68.173.52.158 (talk) 15:44, 9 February 2014 (UTC)

Radius
Primefac, do you know HE 1523-0901 is 37.41 Times Larger Than Our Sun? Kepler-78b (talk) 02:28, 27 August 2021 (UTC)
 * No, but I do now. Primefac (talk) 10:13, 27 August 2021 (UTC)
