Beenay discovers orbital anomaly
Beenay 25, a young astronomer at Saro University Observatory, discovers a discrepancy in his calculations of Kalgash's orbit around Onos. The numbers do not fit the Theory of Universal Gravitation, which is the foundation of modern astronomy. He is deeply troubled, fearing he has made an error or, worse, that the theory is wrong. He asks two brilliant graduate students, Faro 24 and Yimot 70, to independently verify his findings, hoping they will find a mistake.
