How long does it take for light from the Sun to reach Earth?
Answer
8.3 minutes
Light from the Sun takes approximately 8 minutes and 20 seconds to reach Earth, traveling 150 million kilometers through space. This distance is defined as 1 Astronomical Unit (AU) and serves as the baseline measurement for distances within our solar system. The delay explains why we always see the Sun's position as it was 8 minutes in the past.
