Long Lost Star Catalog Found in Plain Sight Space

Webb29 maj 2024 · The most explicit statement about Hipparchus’ star catalog is found in Pliny, who says that Hipparchus noticed a new star and, because it moved, began to wonder whether other fixed stars move; he therefore decided to number and name the fixed stars for posterity, inventing instruments to mark the positions and sizes of each. … WebbHipparchus went on to catalog roughly 850 stars across the night sky, noting their precise locations and brightnesses. By comparing his complete star chart with more fragmentary measurements of individual stars taken by past astronomers, Hipparchus realized that the distant stars had appeared to move 2 degrees from their original positions. omagh chiropractic clinic

His original catalog no longer exists. Ptolemy depended on it massively when he compiled a larger catalog in his Almagest 300 years later. is anything open near me
