How fast does light travel from the Sun to the outer planets?
Quick Answer
Light takes minutes to reach the inner Solar System and hours to reach the outer planets, with the timing depending on distance.
The Full Story
Sunlight reaches Earth in about 8 minutes 20 seconds, but the delay becomes much longer farther out. It takes roughly 43 minutes to reach Jupiter, about 1 hour 18 minutes to reach Saturn, around 2 hours 15 minutes to reach Uranus, and about 4 hours 10 minutes to reach Neptune. That means when astronomers look at distant planets, they are seeing them as they were hours ago. This light-time delay also matters for spacecraft communication and navigation.
