Asteroid satellite: While on its way to Jupiter in 1993, the Galileo spacecraft made a flyby of asteroid Ida. Images captured (Fig. P5.66) of Ida discovered that the asteroid has a tiny moon of its own, since given the name Dactyl. Measurements found that Ida to be about 55 × 24 × 22 km in size, and that Dactyl’s orbit period and radius are approximately 27 h and 94 km respectively. From this data determine Ida’s approximate
