It's not that the sun's shape doesn't change - it's held in a roughly spherical shape by its own gravitation and rotation, but any variations would be so small that we wouldn't be able to see them without a telescope.
because of the suns reflections
the suns have never won a championship
It just appears to change shape but it never physically changes shape unless it's hit by something.
Stars are distant suns, which are roughly spherical in shape.
The moon never changes shape only the light you can see.
what two ways does the suns position change in the sky
The moon never actually changes shape. What we can see at night is the suns reflection from around on the other side of the earth onto the moon, which depending on its position will give us what we can see of the moon at night.
The suns have never won the finals against any team
Never.
what is the shape of the sun? the shape of the sun is a 3d shape and it is a sphere.
No because you were born with a bellybutton that same shape and you can never change it. Ever!
Gases can NOT change shape because gases don't have a 'shape', it's the container in which they are held that has a shape)
