Why do the sun and moon change their size​

Answer 1

Explanation:

When the moon is near the horizon, the ground and horizon make the moon appear relatively close. Because the moon is changing its apparent position in depth while the light stimulus remains constant, the brain's size-distance mechanism changes its perceived size and makes the moon appear very large.All stars change size over their lifetimes, but the sun is currently very stable. Evidence indicates the sun has a constant diameter of about 1.4 million kilometers. The only reasonable explanation for the change in the sun's apparent size is that Earth's distance from the sun changes in a regular pattern.
