Here is the proper write-up explaining the details.
As Earth orbits the sun, this tilt remains fixed in space, causing different hemispheres to "lean" toward or away from the sun at different points in the year. In January: What Causes the Seasons? | NASA Space Place what season are we closest to the sun
We are closest to the sun in , which is winter for the Northern Hemisphere and summer for the Southern Hemisphere. The seasons are determined by the tilt of Earth's axis, not our distance from the sun. The small variation in distance from perihelion to aphelion is secondary to the powerful effect of the sun's angle of incidence. Here is the proper write-up explaining the details
The misconception that we are farther from the sun in winter arises from a logical, but incorrect, intuitive leap: "Winter is cold, so we must be farther from the sun." | NASA Space Place We are closest to
