How this list was compiled: Written for this site; nothing was copied from another list. Questions and wrong choices are our own. Each explanation restates, in our own sentences, a fact from the English Wikipedia article named and linked beside the question (https://en.wikipedia.org, text under the Creative Commons Attribution-ShareAlike 4.0 license), and the passage that states each fact was found in that article on October 15, 2026 before the question was kept. 55 articles are linked, none for more than two questions. The pack covers the 88 constellations recognized by the International Astronomical Union: the list itself, the brightest stars, the myths behind the names, the constellations of the zodiac and finding your way round the northern and southern sky. A myth is told as the linked article tells it, and where the article gives more than one version the explanation says so. Nothing about astrology is asked, and no distance in light-years is asked or stated. A sentence that carries a citation-needed tag in its article was not used. Levels are our estimate: easy is fair for any table, medium suits someone who knows a few constellations, hard will stump most tables. Each question also carries the date its article was read.
