In an experiment in the field of astronomy, an astronomer calculates the distance between Earth and a natural satellite of a planet in our solar system. He uses the order of magnitude to facilitate the understanding of his data and interaction with his colleagues. The calculated distance is approximately 9,461 × km. (a) Determine the order of magnitude of this distance. (b) Suppose the distance between Earth and another satellite is 3.05 × km. In comparative terms, what is the order of magnitude of the difference in distances between the two satellites? (c) If the speed of light is approximately 3.0 × km/s, what is the order of magnitude of the time it takes for light to travel the distance between Earth and the first satellite?
