Asteroid satellite. While on its way to Jupiter in 1993, the Galileo spacecraft made a fly by of asteroid Ida. Images captured of Ida (Fig. P5.66) showed that the asteroid has a tiny moon of its own, since given the name Dactyl. Measurements found Ida to be about 56 ?? 24 ?? 21 km (35 ?? 15 ?? 13 mi) in size, and Dactyl???s orbital period and radius are approximately 27 h and 95 km, respectively. From these data, determine Ida???s approximate mass and density
