Earth farthest from sun
Planet Earth will attain aphelion – when Earth is farthest from the sun – at 20 UTC at the moment (3 p.m. CDT) when it’s 94,506,364 miles (152,093,251 km) from the sun. It’s been a scorching summer season already in elements of the Northern Hemisphere. And Earth’s aphelion all the time is available in July, within the midst of Northern Hemisphere summer season (and Southern Hemisphere winter). So you already know our distance from the sun doesn’t cause Earth’s seasons.
In reality, Earth’s orbit is sort of, however not fairly, round. So general, our distance from the sun doesn’t change a lot percentage-wise (a bit over 3%). Right this moment, we’re about three million miles (5 million km) farther from the sun than we will likely be six months from now. And it’s in distinction to our common distance from the sun of about 93 million miles (150 million km).
By the way in which, the phrase aphelion comes from the Greek phrases apo that means away, off, aside and helios, for the Greek god of the sun. Aside from the sun. That’s us, round now.
What causes the seasons?
The seasons aren’t as a consequence of Earth’s altering distance from the sun. In reality, we’re all the time farthest from the sun in early July throughout northern summer season and closest in January throughout northern winter.
As a substitute, the seasons outcome from Earth’s tilt on its axis. Proper now, it’s summer season within the Northern Hemisphere as a result of the northern a part of Earth is tilted most towards the sun. We’re receiving the sun’s rays most immediately
In the meantime, it’s winter within the Southern Hemisphere as a result of the southern a part of Earth is tilted most away from the sun. The extra oblique daylight causes cooler temperatures.

Earth’s various distance from the sun does have an effect on the size of the seasons, although. That’s as a result of, at our farthest from the sun, like now, Earth is touring most slowly in its orbit. Consequently, that makes summer season the longest season within the Northern Hemisphere and winter the longest season on the southern half of the globe.
Conversely, winter is the shortest season within the Northern Hemisphere, and summer season is the shortest within the Southern Hemisphere, in every occasion by almost 5 days.

Closest and farthest factors tied to solstices?
The quick reply is not any. It’s true that Earth is farthest from the sun yearly in early July, about two weeks after the June solstice. And it’s true that Earth is closest to the sun yearly in early January, about two weeks after the December solstice. Is it a coincidence? Sure, it’s. Over the lengthy course of time, the dates of Earth’s closest and farthest factors to the sun shift with respect to the solstices.
In keeping with timeanddate.com:
As a result of variations within the eccentricity of the Earth’s orbit, the dates when the Earth reaches its perihelion or aphelion are usually not mounted. In 1246, the December solstice was on the identical day because the Earth reached its perihelion. Since then, the perihelion and aphelion dates have drifted by a day each 58 years. Within the quick time period, the dates can differ as much as two days from one 12 months to a different.
Mathematicians and astronomers estimate that in 6430, over 4000 years from now, the perihelion will coincide with the March equinox.
