Because the Earth is closest to the Sun only once per year and it happens in January.
The distance varies by 2.5 million kilometres above and below the average of 149.6 million kilometres.

∙ 9y agoThe seasons have NOTHING TO DO with the distance from the Sun. They are related to the inclination of Earth's axis of rotation. The effect on temperature caused by the distance to the Sun is insignificant, compared to the effect of the seasons.

∙ 8y agoBecause of the tilt of the earths axis the suns rays strike the earth at a more oblique angle during winter months. This happens to be when the earth is closest to the sun for the northern hemisphere.

The same reason why when the Earth is farthest from the sun, the northern hemisphere
is in Summer.
The reason is that the change in Earth's distance from the sun is less than 3.4% between
nearest and farthest. The effect of that difference on temperatures is much smaller than
the effect of the tilt of Earth's axis relative to the plane of the ecliptic, and the resulting
change in the angle of solar radiation at various latitudes.

That's the situation from roughly September 22 until roughly March 21.

What month is it when neither half is tilted toward the sun?
June
Is it night time in ALL parts of the world in th SAME time?
No. Day and night is determined by what part of Earth is facing the sun. Half of the Earth faces toward the sun and half of earth faces away from the sun. As the Earth spins on it's axis, we get daylight in one side of the earth, and night time in the other side of the earth. It is never possible to have night time, or day time, on all the earth at the exact same time.
What is the phase when you see half the moon or earth?
Half-moon Half-Earth
During what season is Earth tilted the least?
The 'tilt' of the Earth's axis doesn't change. The axis always makes an angle of about 661/2 degrees with the plane of the Earth's orbit, and the north pole is always pointed toward the same spot in the sky, near the star Polaris. But as we ride around the sun in the course of a year, since the axis always points toward the same place, that means that the north pole is tilted toward the sun during half of the trip, and away from the sun during the other half. And there are two moments during the year when the axis is neither toward nor away from the sun ... those are always around March 21 and September 22. If you're on the half of Earth that's tilted toward the sun, then you have Spring and Summer. And if you're on the half of Earth that's tilted away from the sun, then you have Fall and Winter. (It has nothing to do with being closer or farther from the sun. It's all on account of the tilt.)
How much of earth is in sunlight when a autumnal equinox occurs?
Half of Earth is illuminated by the sun at all times.
When the northern half of earth tilts toward the sun it has?
The better question would be is if it's possible for you to form a coherent thought, because this question is not one.
In June is the southern half of Earth tilted toward or away from the sun?
Away.
How does winter and summer happen?
You've probably noticed that it gets warmer in summer and colder in the winter. This change happens every year. It happens because the earth tilts back and forth as it goes around the sun. During the summer, the earth tilts toward the sun, which makes half of the earth hotter - this is what we call summer. During the other half of the year, the earth tilts away from the sun, which makes that half of the earth cooler. We call this winter.Did you know that different parts of the world have winter and summer at different times of the year? In the northern half of the world (such as North America and Europe), winter happens during the months of December, January and February. In the southern half of the world (such as South America and Australia), winter happens during the months of June, July and August. Winter happens at different times because the top and bottom halves of the earth tilt away from the sun at different times of the year.
During winter months does earth travel away from the sun?
If one end of the earth's axis is leaning away from the sun, then the other end must be leaning toward it. Whichever half of the earth happens to be leaning away has Winter, while the half that's leaning toward the sun at the same time has Summer at the same time.
What month is it when neither half is tilted toward the sun?
June
What is the earth doing to have 4 seasons?
The Earth has 4 seasons because of its axial tilt of 23 and a half degrees to the plane of the ecliptic, which causes the northern and southern hemispheres to alternately point partially toward and away from the sun.
Is the Earth's northern hemisphere is tilted away from the sun or toward the sun?
Away for half of the year, and toward for the other half of the year.
Why do shadows in the southern half of Australia point south at midday?
There is more daylight on the south of the equator due to the tilt of the earth. The earth tilts toward the sun in the southern hemisphere, and away from the sun in the northern hemisphere.
Is the half of earth where its nighttime facing toward the sun or away?
Away
What are the reasons earth has seasons?
I asked this at school not that long ago, and I think it was something to do with how the earth tilts towards the sun. So when the top or bottom half of the earth is facing the sun its hotter.. but I'm not quite sure.
What is true when northern half of earth is tilted toward the sun?
it is summer in the northern hemisphere
How do climatic condition of earth affected by the rotation of earth's axis?
the climactic conditions change on earth because when the earth spins it tilts back and forth like a top that is about to fall over(but the earth is going to fall over!) and when it tilts back and forth like this is causes one half of the world to move down(causing summer because that part of the earth is closer to the sun) and the other side of the earth to move up(casuing that side of the earth to be farther away from the sun causing winter because there inst as much sunlight)
