The Sun looks bigger because of an optical illusion. When the Sun is near the horizon, it sometimes seems to be much bigger and closer than during the rest of the day. Ats unrise or sunset, your brain has other objects to compare the Sun’s size to, such as trees and buildings.

When the sun (or moon) is near the horizon there are things along the horizon to compare size to, whereas when the sun or moon are higher in the sky they are dominated by the emptiness around them and appear smaller.

The sun (or moon) is actually a bit closer to you at noon (by the radius of the Earth), so it is actually larger then...but only by 4/9300 as much.

If you hold your index finger at arm's length up to the moon, you might be amazed to find that it takes four moons to equal the width of your finger. This is a handy tool to remember, because if some object in the sky is, say, six degrees from some others, you can use your fingers as a guide.

it is the same like your shadow. when the sun is right up your head.shadow looks small and when fro or back looks big

the serious answer is that during afternoon the sun has just started to move away that is to set and evening it is already set and some darkness has taken place up in the sky so we are able to see clearly and afternoon we are not able to see bcoz there is no darkness
for ex
taking light from a watch . when u go see in the afternnon in that bright sun u cant see clearly. then enter a dark room u can see clearly this is the same as u asked
a good question
aadarsh.
brilliant question

It is mainly due to refraction of light rays through the atmosphere.When the sun is overhead, the thickness of atmosphere through which the rays pass through is less and the refraction is also less.So the size is also less. During sunset the rays have to pass through more atmosphere and the refraction is also more.The refraction occurs in such a way that the smaller sun overhed is shown as bigger one at the sunset.

the sky acts as a magnifier during the afternoon there is less atmosphere thickness approximately 3-5 miles to act on the size -and this is the actual size it looks like in space-vs- the evening in which the the thickness is hundreds of miles due to the angle it pierces thru.also it is dimmer just before sunset or sunrise.due to how thick the atmosphere pierce angle is.

For the same reason as the moon in its size....light refraction as it passes through the earths atmosphere.
As in the case of looking at a fish in water say at a distance of six feet...when light travels through the air it ia constant and as it hits the water it doesnt bend but angles away

A sun on the horizon appears a shorter distance than when it is at high noon, straight above.

It is in the same size only. Daytime you cannot have straight view because of the heat.

we are not exactly in the middle of the suns orbit so when it goes around its closer at night
