galaxyDistance関数
リファレンスの説明と例は英語です。見出しと目次は日本語です。
The distance to a Messier, NGC or IC galaxy: the median of the distances Wikidata (CC0) gives, in light-years and parsecs, with the error where a statement has one, the lowest and highest statement, how many there are and whether they disagree (the highest more than 1.2 times the lowest). The method is always "compiled, method not stated": Wikidata gathers published values and names no method. About six in ten of the galaxies have one. Statements Wikidata marks deprecated are not used, and neither is any under 20 kiloparsecs (the nearest galaxy in the lists is the Small Magellanic Cloud, at 60).
