Here's why:
* The Moon's Orbit: The moon's orbit around Earth is not a perfect circle, but rather an ellipse.
* Perigee and Apogee: The point where the moon is closest to Earth is called perigee, and the point where it is furthest is called apogee.
* Apparent Size: Because the moon's distance from Earth varies, its apparent size in the sky changes. When it's closer (at perigee), it appears larger. When it's further (at apogee), it appears smaller.
Important Note: While the moon's apparent size is affected by its distance, it's important to remember that the difference in size between the moon at perigee and apogee is not always dramatic and can be difficult to notice with the naked eye.
