Chapter 25: Problem 5: In the year 1178, five monks at Canterbury Cathedral in England observed what appeared to be an asteroid colliding with the moon, causing a red glow in and around it. It is hypothesized that this event created the crater Giordano Bruno, which is right on the edge of the area we can usually see from Earth. a)  How long after the asteroid hit the Moon, which is 3.84 ×10⁵ km away, would the light first arrive on Earth in seconds?
