because the earth is "tilted" 23.5 degrees. So, when earth rotates around the sun, it is either tilted closer, or farther away from the sun. For example, in summer, earth is titled towards the sun, making shadows short. But in winter, earth is tilted farther from the sun. So shadows are longer. That is why shadows are longer or shorter during the year.

what causes shadow length?
The length of an object's shadow is determined by ... -- the length of the object, -- the angle between the object's length and the surface on which its shadow appears, -- the distance between the object and the surface on which its shadow appears, -- the angular size of the light source as seen from the object, -- the angle between the direction to the light source and the normal to the object.

Is position of the constellation seem to change thoughout the year?
Only if you look at it at the same time every night. If you look at it 4 minutes earlier each night, then it doesn't change position at all.

Do the day lengths change throughout the year because of the earths tilt?
Yes. We could write a lot more, but yes is the answer.
What are the lengths of shadow during the day?
There is no one answer to that as we'd need to know your height and location and at what time of the year to give a precise answer. Generally, though, we can say that at high-noon in summer, your shadow will have minimal length as the sun is more directly above you. At high-noon in winter, your shadow will be longer as the sun is much lower in the sky than in summer. Your shadow is longest at sunrise and sunset and will shorten until high-noon after which it will lengthen.
Does the day lengths change throughout the year because of the earths tilt?
Yes/more at the north/south hemisphere zones but almost constant at the equator.
