They're both places in the Earth's orbit around the sun.
"Perihelion" is the point where the Earth is closest to the sun. We reach
that point at some moment during the first couple days of January.
"Aphelion" is the point where the Earth is farthest from the sun. We reach
that point at some moment during the first few days of July.
Also, these terms are used for other members of the solar system. That's
the other planets, asteroids, comets, etc.
Earth's distance from the Sun at aphelion, which occurs in early July, does not significantly impact global temperatures. The difference in distance (about 3 million miles) is relatively small compared to the overall energy received from the Sun. Seasonal variations, primarily driven by axial tilt, have a more substantial influence on Earth's climate than the minor changes in distance at aphelion or perihelion. Thus, aphelion does not lead to an overall cooling of the planet.
Pluto's perihelion distance is about 4.4 billion kilometers, while its aphelion distance is about 7.4 billion kilometers from the Sun. So, Pluto is closer to the Sun at perihelion and farther away at aphelion.
A planet's maximum distance from the Sun is known as its aphelion. This point occurs when the planet is at the farthest point in its elliptical orbit around the Sun. The distance between the planet and the Sun is greatest at aphelion.
Saturn's aphelion is when Saturn is farthest from the Sun.At that point it is about 1,513,326,000 km (10.1 AU) away from our star (measured from center of mass to center of mass).
Mars is about 154 million miles (249 million kilometers) away from the sun at its aphelion, which is the farthest point in its orbit around the sun. This distance varies slightly due to Mars' elliptical orbit.
Winter. In the beginning of January, the Earth is closest to the sun.
152,098,232 kilometers.
Aphelion, which generally occurs in July.
Yes, it actually is. The difference between earth's closest approach to the sun (perihelion) and its farthest approach to the sun (aphelion) is more than 3.1 million miles.
In elliptical orbits, all bodies travel faster when nearest the "primary"; in this case, the Sun. Since the Earth's orbit isn't very eccentric (meaning that it is almost but not quite circular) the difference between perihelion velocity and aphelion velocity isn't very great.
The Aphelion.
Aphelion is the point in a planet's or comet's orbit where it is farthest from the Sun. The Earth's aphelion is 152,098,232 km.

Aphelion
The distance between Earth and the Sun during aphelion and perihelion affects the temperature on our planet because when Earth is at aphelion (farthest from the Sun), it receives less solar energy, leading to slightly cooler temperatures. Conversely, when Earth is at perihelion (closest to the Sun), it receives more solar energy, resulting in slightly warmer temperatures.
A planet's maximum distance from the Sun is known as its aphelion. This point occurs when the planet is at the farthest point in its elliptical orbit around the Sun. The distance between the planet and the Sun is greatest at aphelion.
