Earth is closest to the Sun at perihelion in January, but it’s winter in the Northern Hemisphere because the planet’s axial tilt causes seasonal changes, not its distance from the Sun. The tilt results in varying sunlight exposure, creating summer and winter, while the elliptical orbit’s slight distance variation has minimal impact on temperatures.
Earth's closest approach to the Sun, called perihelion, occurs during winter in the Northern Hemisphere due to the Earth's axial tilt and elliptical orbit, which causes seasonal variations in sunlight exposure. This timing is a coincidence and varies over thousands of years due to gravitational influences and orbital changes.
Today is Aphelion Day, the point in Earth's orbit when it is farthest away from the Sun. Earth will be 94,506,364 miles from the Sun at 4:06 p.m. EDT. However, Earth's distance from the Sun does not solely determine seasons; they are primarily influenced by the axial tilt of the Earth. The Northern Hemisphere experiences summer when its axis points towards the Sun, and the abundance of landmass in that hemisphere contributes to the higher temperatures.
