Why is the moon sideways?

The moon hasn't changed. It's the lighting.

You see a "new moon" when the moon sets shortly after the sun sets. The visible crescent is a result of the sun light reflecting off of the moon.

The point on the horizon where the sun sets moves north and south with the seasons. The place where the moon sets moves around, too. Whenever, by coincidence and orbital mechanics, the moon sets at the same point where the sun sets, the moon is illuminated from the bottom, and you see the "smile" as in your picture.

If the sun had set to the right of the point where the moon is setting, you'd see the crescent on the right (horns pointing to the left).

The moon has behaved exactly the same way for about 4 <<billion>> years. There is no change. The lit side is the part that is facing toward the sun. At the time you took that picture, the sun would appear to be pretty close to being directly opposite you on the other side of the earth.

If it appears to be sideways, then it is only because you don't happen to see it very often in that specific configuration.

There is nothing abnormal about it for that time and place.

We see the moon because of the sunlight it reflects.

The moon is not sideways - the moon is reflecting sunlight and right now the sun is at a steep angle to the moon.

Happens for about half the year.

The moon isn't sideways... you are.

i think it is cause the sun or clod hit it
