I just watched the episode and reviewed the episode transcript, and I can't seem to confirm the following reference as canon -- specifically the year, or the fact that it was the Nausicaans who attacked the ship:

"In 2147 she was destroyed by Nausicaan pirates."
There is no such quote in the episode. It is never specifically said then the North Star was destroyed or that caused by Nausicaan attack. 23:59, April 12, 2012 (UTC)
Which is probably why it was removed from the article in 2005. 31dot 00:05, April 13, 2012 (UTC)
I've taken the liberty of removing this unsubstantiated claim from the article. 05:18, July 16, 2014 (UTC)
