An astronomer on Earth observes a meteoroid in the southern sky approaching the Earth at a speed of 0.710c. At the time of its discovery the meteroid is 19.5 lightyears from the Earth. (a) Calculate the time interval required for the meteroid to reach the Earth as measured by Earthbound astronomer. 14.79 X Your response differs from the correct answer by more than 10%. Double check your calculations. yr (b) Calculate this time interval as measured by a tourist on the meteroid. yr (c) Calculate the distance to the Earth as measured by a tourist on the meteroid.
