when it is winter on the north part of the globe, is it closer or further from the sun than the south part?

Answer 1

Further, due to the tilt as it rotates.

Answer 2

Combine the answers from Jason and Mitch. The North will be slightly further from the sun due to the tilt. This would be less than the radius of the Earth.
At perihelion the Earth is 147.5 million kilometers from the sun. This happened in 2007 on January 3rd. At aphelion the Earth is 152.6 million kilometers from the sun. This will happen on July 7th.
The difference in distance is 5.1 million kilometers, much more than the radius of the Earth.
The tilt away from the sun's warmth has much more to do with the reason for winter than the distance from the sun.

Answer 3

During the northern winter months the Earth is closer to the sun than in the summer months, but the northern hemisphere is tilted away from the sun, while the southern hemisphere is tilted towards the sun.

Answer 4

the north pole is tilting away from the sun during December when it it winter in the Northern hemisphere so you could say that it's slightly further, but it's the fact that it isn't as exposed to the sun that it's winter.

Answer 5

Gene is correct. It is winter and cold due to the angle caused by earth's tilt on its axis, but is closer to the sun.

Answer 6

Winter is December 21st to March 21st. The 21 may be 20 depending where we are in the leap year 4 year cycle. During this time of the orbit, the earth is close to the sun.
