The sun, although a very energetic stellar body, actually is pretty constant in it's size.

What is the suns length of day?

I think that the sun doesn't have any length of day, because of the heat and how the planets revolve around the sun.


What is the day length from earth to the sun?

shorter


What is the relationship between earth day length and the distance from the sun?

There is no direct relationship between the rotation of a planet (which governs day length) and a planets distance from the sun. The nature of the planets spin is more to do with the formation of the system early on, by large impacts of the more numerous bodies that would have been around.


How will the length of day and night change if the sun increases in size?

If the sun increases in size but nothing else changes, then there will be no change in the lengths of day and night. However, the gravitational and tidal effects of changes in the sun's size is likely to affect the earth's rotational period and its orbit.


Is the length of the day the factor that governs the seasons?

The length of the day is not the reason but is a result of the season. The reason for seasons to take place is the inequality of distance between sun and earth with time. We all know that earth rotates around sun. But it won't rotate in a perfect circular path. The orbit of earth is an oval in shape. Hence, some times it will be closer to sun and some times farther. When it is closer, most of the area on earth is covered by sun. Hence, we have more day time (or length of the day) during summer. In a similar manner, as less area is covered by sun, the length of the day is less in winter.

Does the length of your shadow change throughout the day is that a scientific answer?

Yes, the length of your shadow changes throughout the day due to the changing position of the sun in the sky. Shadows are longest in the morning and evening when the sun is lower in the sky, and shortest at noon when the sun is directly overhead.


How does the planets distance from the sun affect the length of a day?

Not at all. The planet's daily rotation is independent of its distance from the Sun.


How much earlier does the moon rise each day as you approach Spring Equinox?

Sun rises and set due to rotation of earth. As sun moves from equator length of day increases or decreases depend upon which hemisphere sun is i.e. deceleration of sun. Length of the day rapidly increases towards the pole. As per your question it depended upon your position w.r.t. latitude. If you are close to pole length of the day increases more than if you are close to equator.


What causes differences in day length?

The elliptical orbit of the Earth around the Sun.


Does the sun's position in the sky affect the length of daylight?

Yes, the sun's position in the sky affects the length of daylight. The angle at which the sun's rays hit the Earth's surface changes throughout the day due to the Earth's rotation, which in turn affects the length of daylight hours.


How does the length of your shadow change in the day?

The length of your shadow changes throughout the day due to the angle of the sun in the sky. Your shadow is longest when the sun is low in the sky, typically early morning and late afternoon, and shortest when the sun is directly overhead around midday. This is because the higher the sun is in the sky, the shorter the shadow it creates.
