How to read this chart: Every bar starts from the same baseline on the same scale, so length maps directly to value. Compare lengths; the sorting is already done for you. More on ranked bars charts.
The takeaway
Sunlight reaches Mercury in about 3 minutes and Earth in about 8. Neptune, 30 times farther out, waits more than 4 hours.

How we counted
How we counted: each time is the planet's average distance from the Sun (NASA planetary fact sheet) divided by the speed of light, 299,792 km per second. Average distances: Mercury 58 million km, Earth 150 million km, Neptune 4,515 million km. Planets orbit in ovals, so the real wait shifts through the year: Mars, for example, is 11.5 to 13.9 minutes.

What the numbers show
Sunlight takes about 8.3 minutes to reach Earth. Closer to the Sun, Mercury gets it in 3.2 minutes and Venus in 6. Farther out, the wait grows fast: Mars waits 12.7 minutes, Jupiter 43.3, Saturn 79.6 and Uranus 159. Neptune, the farthest planet, waits 251 minutes, which is more than 4 hours.
The reason is distance. Light always travels at the same speed, 299,792 km per second, so the wait grows in step with how far a planet sits from the Sun. Mercury is 58 million km away and Earth is 150 million km away. Neptune is 4,515 million km away, about 30 times Earth's distance. That is why its wait is also more than 30 times Earth's.
NASA's planet pages state these times in rounded form: 3.2 minutes for Mercury, about 6 for Venus, about 8 for Earth, 13 for Mars, 43 for Jupiter and 80 for Saturn. They give 2 hours and 40 minutes for Uranus and 4 hours for Neptune. Our figures come from NASA's planetary fact sheet. It lists each planet's average distance from the Sun, and we divided that by the speed of light. The two agree to within a minute or so. A second site, Sterngucker, lists the same times, with Uranus at 2 hours 39 minutes and Neptune at 4 hours 11 minutes.
These are averages. Planets travel in ovals, not circles, so their distance from the Sun changes through each year. Mars, for example, is 11.5 minutes from the Sun at its closest and 13.9 minutes at its farthest. The same is true of every planet, so the wait on a given day can differ a little from the numbers here.
To read the chart, compare each planet with Earth. A wait of 8.3 minutes is the baseline. Jupiter, at 43.3 minutes, waits about five times as long. Saturn, at 79.6 minutes, waits nearly ten times as long. Uranus, at 159 minutes, waits about 19 times as long. Neptune, at 251 minutes, waits more than 30 times as long. Because the light left the Sun before it arrives, the Sun that Neptune receives is the Sun as it was more than 4 hours earlier.

Sunlight takes 8.3 minutes to reach Earth. The farthest planet waits 30 times longer.
Mercury gets sunlight in 3.2 minutes, Venus in 6, and Earth in 8. Mars waits 13, Jupiter 43, Saturn 80, and Uranus 159. Neptune, the farthest planet, waits 251 minutes. That is more than — 30 times longer than Earth.
