An anthelion is a very fancy word for something that can happen in the sky. Sometimes when the sun shines through tiny little ice crystals in the air, it can create a special kind of light show up in the sky called an anthelion. It looks like a bright spot of light that's opposite the sun. It's like the sun has a special friend that always follows it around. This friend can be different colors too, like pink or purple. It's kind of like having a special secret that only the sun and its friend know about.
