Are the moon and the sun bigger on the horizon than after rising?

The "scenes in the sky" such as the moon, sun and constellations are bigger when they are close to the horizon than when they rise to high places.

The sun on the horizon looks bigger, which is just an optical illusion. The brain thinks that objects on the horizon can see farther than those overhead. Because whether on the horizon or in the air, the size of the sun remains the same, and the brain reflects that the sun on the horizon is bigger, which makes you feel that the sun has a bigger perspective. This phenomenon is called Ponzo illusion and can also be used for the moon illusion.

If you don't believe me, look down at the sun hanging upside down between your legs. At this time, the sun on the horizon looks as big as the one above you.

Direct observation of the sun, moon and sky with naked eyes requires certain conditions. Generally, it can only be seen in broad daylight when the sky is clear and the visibility is good from February/Kloc-0 to March in the autumn lunar calendar.

As long as two conditions are met, you can see the landscape where the sun and the moon appear at the same time. The first is the angular distance between them. Angular distance refers to the angle and distance between the sun and the moon in the sky. When the angle between them is between 120 degrees and 170 degrees, the first condition is satisfied when the distance is appropriate.

Secondly, it's sunny. If you want to see the sun and the moon in the sky at the same time, it must be sunny that day. After the gale began last night, the smog in the sky has been blown away, revealing a rare sunny day in the sky.
