What days in year can I see the sun-set apeears in largest size?

Question

Sun rise, sun set

Answer 1

The point at which the earth is nearest the sun is called perihelion and this occurs on about 5th January each year (it varies from year to year, this year it was 3rd Jan, last tear it was 4th Jan).

The earth has an average distance of 93.0 million miles from the sun, at perihelion it is 91.3 million miles, at aphelion, when the earth is furthest from the sun, it is 94.4 million miles.

Being closer to the sun will of course make it look bigger but atmospheric conditions can cause an optical illusion. If there is a lot of dust or pollution in the air this can distort the image of the sun and make it look larger than usual.

Answer 2

as the precedent message stressed it, apparent size of the sun will not vary much with the time of the year due to the distance.

the main factor to get an apparent increase of the size of the sun are :
- sun low on horizon (comparizon with human made objects or animals increase the apparent size)
- hazy weather turning the sun a little bit red
- good composition with a far away - wide open landscape reducing the apparent size of the landscape.
