Answer:
Harry's hair is the night, his eyes the stars, and his smile the bright crescent moon.
Step-by-step explanation:
We are comparing the color and quality of harry's hair to the night sky, meaning his hair is dark, we are comparing his eyes to the stars meaning they reflect the light and look like they are shining and we are comparing his smile to the "bright" crescent moon meaning his smile is wide, white and bright.
