Question

On what date, according to the "cosmic calendar", did an asteroid strike Earth?

Answer 1

The light from the asteroid collision on the Moon would take approximately 1.28 seconds to reach Earth.

Step-by-step explanation:

The distance between the Moon and Earth is approximately 3.84 × 105 km. The light from the asteroid collision on the Moon would take approximately 1.28 seconds to reach Earth.

Light travels at a speed of about 300,000 km/s. To calculate how long it takes for light from the asteroid collision on the Moon to reach Earth, we can use the formula:

Time = Distance / Speed

Plugging in the values gives:

Time = 3.84 × 105 km / 300,000 km/s = 1.28 seconds

Therefore, it would take approximately 1.28 seconds for the light from the asteroid collision on the Moon to reach Earth.
