This video discusses the scale of the earth and sun, and how far away they are from each other. The sun is 109 times the circumference of the earth, and it would take 4,000 hours to circumnavigate it. The earth is 150 million kilometers away from the sun, and if you were to shoot a bullet or a jet plane at the sun, it would take 17 years to get there. The scale of the universe is vast, and the distances between objects are vast as well. The sun is just one of many objects in the universe, and if it were to disappear, it would take eight minutes for us to know it had disappeared.
