The distance from the Sun to Neptune is 4,504,300,000 kms Light travels 9,460,730,472,580,800 kms a year So light would take just over four hours to get from the Sun to Neptune. Most of us have taken a 4-hour road trip. So imagine driving solidly for over four years. That's how long you'd have to travel for (at the speed of light) to get to the next star (Proxima Centauri).
The time would be T= d/c where d is the distance between Earth and Neptune and c is the speed of light.
The light wakes you up because you are very sensitive to the light when you first wake up. Your eyes have been in darkness for a long period of time and now light is hitting them.
Thew width of Neptune is exactly 72.9m long

In terms of daylight and darkness, that will depend on where in the world you are. If you are in the Antarctic, then it is bright all of the time, with no darkness, in January and completely dark with almost no light in July. It would be the reverse in the Arctic. If you were on the equator, it would be about 12 hours of light and 12 hours of darkness all year. Between the equator and the poles, the amount of darkness and daylight will vary, getting more extreme the closer to the poles you get.

The Great Darkness lasted for three days. It is a symbol of the power of evil and the imminent danger that darkness can bring, as well as a reminder of the eventual triumph of light and goodness over darkness.
When earthworms are in light too long, they become paralyzed, their skin falls off, and then they die.

As the Earth wobbles its way through the universe, it tilts both poles toward and away from the sun.
