Metric Value Note Average Distance 149. Experiencing the Delay Unlike distant stars, the sun’s light travel time creates a tangible effect we can all experience.
Calculating the Astronomical Unit Using Light Speed from Sun to Earth
Earth's orbit is elliptical, not circular, meaning the distance between the sun and Earth varies. Using this fixed value, the astronomical unit (the average sun-Earth distance) is precisely calculated, ensuring that the "8 minutes" figure is a highly accurate estimate derived from defined constants.
We would continue to orbit in darkness and warmth for just over 8 minutes before the change took effect. The Science Behind the 8 Minutes At the heart of this phenomenon is the constant speed of light in a vacuum, which clocks in at approximately 299,792 kilometers per second (186,282 miles per second).
Calculating the Astronomical Unit Using Light Speed from Sun to Earth
Consequently, the exact value of the speed of light is 299,792,458 meters per second. If the sun were to suddenly vanish, gravity and light would require the same 8 minutes and 20 seconds to cease reaching Earth.
