Web27 de ago. de 2024 · Light travels at a speed of 186,000 miles (or 300,000 km) per second. This seems really fast, but objects in space are so far away that it takes a lot of time for their light to reach us. The farther an object is, the farther in the past we see it. Our Sun is the closest star to us. It is about 93 million miles away.
