Detailed explanation-1: -In 2023, Earth is at perihelion on January 4 at 11:17 A.M. Eastern Time and will be at aphelion on July 6 at 4:06 P.M. Eastern Time.

Detailed explanation-2: -The Earth completes one revolution around this oval-shaped orbit each year, and so it makes its closest approach to the Sun on roughly the same day every year. In 2022, this falls on 3 January.

Detailed explanation-3: -aphelion, in astronomy, the point in the orbit of a planet, comet, or other body most distant from the Sun. When Earth is at its aphelion in early July, it is about 4,800,000 km (3,000,000 miles) farther from the Sun than when at its perihelion in early January.

Detailed explanation-4: -Jan. 4, 2023 is known as the perihelion. The Earth is closest to the Sun, at its perihelion. This happens because the Earth’s orbit around the Sun is not a perfect circle.

Detailed explanation-5: -The Earth is closest to the Sun, or at the perihelion, about two weeks after the December solstice, when it is winter in the Northern Hemisphere. Conversely, the Earth is farthest away from the Sun, at the aphelion point, two weeks after the June solstice, when the Northern Hemisphere is enjoying warm summer months.
