ALT1: ... that al-Battani was one the first astronomers to observe that the distance between the Earth and the Sun varies during the year? Source: Citations 3, 17-18
Overall: Recent GA article is very well sourced and has no issues. The sources in the article verify the hook (for example Ref 3 says he "is regarded as the best and most famous astronomer of Medieval Islam"). @Onegreatjoke: The only tweak I would make might be shortening ALT0, I don't think it's necessary to specify "of the known astronomers" since unknown astronomers can't be famous. That's not necessary though since it's well within length limits either way. Otherwise both hooks are very interesting! BuySomeApples (talk) 01:48, 4 March 2023 (UTC)
