    "It is curious at least, that his Philosophy obliged Pythagoras, to make the Solar System #61;10, tho' his imperfect Astrognosy reduced him to the shift of including the moon, and imagining an Antiχθων ["anti-earth, anti-world"] and taking the whole as a completory Unit—Sun, Mer[cury,] Ven[us,] Earth, Moon, Mars, Jupiter, Saturn, Antichthon #61;9#43; Solar Syst[em] #61;1#61;10"

Etymology

From astro- (prefix meaning ‘star’) + -gnosy (suffix denoting the scientific knowledge of a subject), modelled on German Astrognosie, or its etymon Late Latin astrognosia, from Ancient Greek ἄστρον (ástron, “celestial body; (specifically) fixed star; planet”) (ultimately from Proto-Indo-European *h₂eHs- (“to burn; to glow”)) + -γνωσία (-gnōsía) (from γνῶσις (gnôsis, “inquiry; knowledge”), ultimately from Proto-Indo-European *ǵneh₃- (“to know; to recognize”)).
