stephanwant to count number of objects have in space For a first measurement, they count the asteroids for 60 days and detect 1000 objects. Several months later, they start a second measurement: This time, they count for 80 days. How many asteroids will they detect during the second measurement? Explain why. we can consider that the asteroids are homogeneously distributed in their solar system.)
