    246 Asporina is a sizeable main-belt asteroid. It is classified as one of the few A-type asteroids.

    It was discovered by A. Borrelly on 6 March 1885 in Marseilles and was named after Asporina, a goddess worshipped on Mount Asporenus, Asia Minor. [2]

    The spectrum of 246 Asporina reveals the strong presence of the mineral olivine, a relative rarity in the asteroid belt. [3]

    42 Isis is a large main-belt asteroid, measuring 100.2 km in diameter with a stony (S-type) composition. It was discovered by English astronomer N.R. Pogson on 23 May 1856 at Oxford, and was his 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 chosen in homage to Pogson's astronomer daughter, (Elizabeth) Isis Pogson. In addition, the Isis is the stretch of the River Thames that runs through Oxford.
