the light of the sun
The sun is approximately 400 times the size of the moon, however, it is also approximately 400 times farther away. This relationship cancels out and makes the sun and the moon appear observationally to be the same size on earth.
The phase (shape) is due to the position of the sun relative to the Earth and sun. When the Earth is between the sun & the moon, it casts a shadow on the moon's surface - changing the shape of the lighted segment. The difference in size is caused by the path of the moon around the earth. It orbits in an ellipse (egg-shape) - not a circle. This varies the distance from the earth - the closer it is, the larger it appears.
The sun's cure is spherical.
The Moon of the Earth has a spherical shape regardless to its position compared to the Sun.
The sun will never change its size and shape, when the sun was created that's how it came out, no body can go to the sun and see whats there its just sun it has to be alt east half of the earth because it goes around 360 divide it by 2, and it would be half! that's why the sun size and shape cant change!

If the sun's rays are parallel, you get a same size and same (projected) shape. They are pretty much parallel (to each other).
because Chuck Norris said so
Shape: sphere (3-dimentional circle) Size: diameter over 1.3 million km at equator. That's over 100 times the Earth's diameter.
The sun is approximately 400 times the size of the moon, however, it is also approximately 400 times farther away. This relationship cancels out and makes the sun and the moon appear observationally to be the same size on earth.
The 2 properties of solids include a definite size and shape, and ability to keep their own shape.

Pressure caused by high temperatures are balanced by gravity
the way that you stand determines the shape of a shadow.
A liquid has a definite size but no definite shape. In contrast, a solid has definite size and shape, and a gas has no definite size or shape.
