42 Isis

42 Isis (pronounced /ˈaɪsɨs/) is a large main belt asteroid, measuring 100.2km in diameter. It was discovered by N.R. Pogson on May 23, 1856 at Oxford. It was Pogson's first asteroid discovery.

The asteroid's name was chosen by Manuel John Johnson, director of the Radcliffe Observatory in Oxford. Although Isis is the name of an Egyptian goddess, the name was likely chosen as an homage to Pogson's astronomer daughter, Elizabeth Isis Pogson. In addition, The Isis is a stretch of water that runs through Oxford.[3]
