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.

∙ 15y agoThe word "perihelion" is made up of two parts. The Greek prefix "peri", which means "near" or "Surrounding", and the Greek word "helios", meaning the Sun. So "perihelion" means the point in an orbit which is closest to the Sun.
The Greek prefix "apo" means "apart from" or "separate from". So the word "apohelion" is used to mean the point of an orbit that is farthest away from the Sun.
The abbreviation "gee" is sometimes used to refer to the force of gravity, especially the Earth's gravity, and is thereby associated with the Earth. So "perigee" means "the closest approach to Earth" and apogee refers to the farthest point from Earth in a satellite's orbit.

∙ 6y agoAphelion is the point in an orbit around the Sun, when the orbiting object is FARTHEST; at perihelion, the orbiting object is CLOSEST to the Sun.Note: Instead of aphelion and perihelion, you might also use the generic words "apapsis" and "periapsis"; this applies to ANY orbit, and not just an orbit around the Sun.

Is Pluto perihelion or aphelion?
aphelion
How far is mars from the sun in aphelion?
It is about 249,209,000 kilometers from the Sun, at aphelion.
When is Jupiter's 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).
Does a planet travel fastest at aphelion or perihelion?
Neptune is located at aphelion in its orbit. It is the furthest from the Sun while it is in its orbit.
Distance between Earth and Uranus in kilometers?
It will vary quite consideraby depending on the position of each of the Planets.At one point, both planets will be on the same side of the Sun, and the distance will be quite small - astronomically - and at others, Uranus can be on the other side of the Earth at Aphelion, and the Earth on the opposite side of the Sun at Aphelion.So the distance will vary between.Closest: Earth at Aphelion and Uranus at Perihelion. Same sideFurthest: Earth at Aphelion and Uranus at Aphelion. Opposite side.Closest: 2,596,840,229 kmFurthest: 3,156,517,936 km
During which season does the Earth reach periphelion?
Winter. In the beginning of January, the Earth is closest to the sun.
What is the distance between Earth from the sun during aphelion?
152,098,232 kilometers.
Is Pluto perihelion or aphelion?
aphelion
The distance between earth sun is the greastest during?
Aphelion, which generally occurs in July.
Is the northern hemisphere summer during aphelion or perihelion?
The Aphelion.
How do you use the word 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.
In Ontario is the sun actually closer to the earth in winter?
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.
Does earth move faster in its orbit near perihelion (January) or near aphelion (July)?
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.
How far is mars from the sun in aphelion?
It is about 249,209,000 kilometers from the Sun, at aphelion.
When is the distance between the sun and earth greatest?
Aphelion, which happens a few days after the summer solstice in the northern hemisphere.
What is the distance between the Sun and Earth called?
The nearest distance is called the perihelion and the furthest distance is called the aphelion (there is about 5 million km difference). The mean distance is called one astronomical unit.
What is the furthest distance between Uranus and the Sun?
At aphelion, Uranus is 3,004,419,704 km or 20.083 305 26 AU from the Sun.
