Given distance of Beta Andromedae correct or not?[edit]

Hello, I was translating Carl Sagan's thoughts from Cosmos about Beta-Andromedae where he says the star is 75 light years away from us.

The Wikipedia article says it is 200 lya.

I did a quick google search and realized that I don't have reliable sources on this, because many articles, sites and books confirm Sagan's 75 ly, but some confirm Wikipedia's 200 lya.

Could you please investigate this issue and fix the article (if it's erroneous)? — Preceding unsigned comment added by AdamMorva (talkcontribs) 23:50, 24 November 2011 (UTC)

The parallax from 1995 was 0.048", whereas the current parallax estimate is 0.017". These would explain the discrepancy. Sagan's work was based on an older parallax measurement. The current distance estimates reflect the latest results. Regards, RJH (talk) 20:33, 30 March 2012 (UTC)
