Answer:

The sun does not get cold in the winter. The sun is a giant ball of fire driven by nuclear reactions. The surface of the sun stays at an incredibly hot temperature of about 5800 Kelvin all year long. The high temperature of the sun causes it to constantly emit prodigious amounts of thermal radiation in all directions, mostly in the form of infrared waves, visible light, and ultraviolet waves. This radiation spreads throughout our solar system and warms everything it hits.

Regions of earth are colder in the winter because the tilt of the earth causes the sunlight to be spread over a larger area and therefore be weaker per unit area in these regions. Some people think the earth gets colder in the winter because the earth is farther away from the sun, but this idea is wrong. In fact, the earth is farthest from the sun in the northern hemisphere's summer, and not winter. But distance to the sun does not have much effect on the amount of sunlight the earth receives because the distance to the sun does not really change that much. The earth is about 150,000,000 kilometers away from the sun. Over the course of a year, the distance from the earth to the sun changes by at most 5 million kilometers. To put this in perspective, the orbit of the earth around the sun throughout the year is plotted below to scale. You can't tell, but at this scale the earth is 302 pixels from the sun when at the leftmost point in its orbit and 298 pixels from the sun when at the rightmost point.

orbit of earth around sun

The orbit of the earth around the sun, with all sizes and locations to scale. The white dot near the center is the sun, and the blue line is the path of the earth through-out the year. The earth itself is not visible because at this scale it is only 0.02 pixels wide. The distance of the earth from the sun is more or less constant through-out the year.

The axis of earth's rotation is tilted about 23 degrees with respect to its orbit around the sun. This mean's that in the north's summer time, the northern hemisphere is tilted towards the sun and in the winter time, the northern hemisphere is tilted away from the sun. When a region of land is tilted towards the sun in the summer, that means that the sun spends more time higher in the sky and the sunlight received by that spot of land is more direct. In contrast, when that spot on the earth is tilted away from the sun in the winter, the sun is in general lower in the sky, and it receives less direct sunlight. Less direct sunlight means that the sunlight is coming in at a low angle, so that it is
