  • Why Does the Sun Appear Larger at Sunrise and Sunset? - Explained
    The sun doesn't actually change size throughout the day. The apparent change in size is an optical illusion caused by atmospheric refraction.

    Here's how it works:

    * Refraction: Light bends as it passes through different mediums (like air and space). When the sun is near the horizon, its light has to travel through a larger amount of air at an angle.

    * Bending: This bending of light makes the sun appear higher in the sky than it actually is.

    * Apparent Size: Because the sun appears higher, its light rays are spread out over a larger area, making it seem larger.

    In contrast, at noon:

    * The sun is directly overhead, so its light travels through less air and is bent less.

    * This results in a less distorted view of the sun, making it appear smaller.

    It's important to note: The sun's actual size doesn't change. The illusion of it being bigger at sunrise and sunset is a result of how light behaves in the atmosphere.
