Perihelion is the point in an object's orbit around the sun where it is closest to the sun.
Comes from greek peri- =near
Anahelion is the opposite--the point in an object's orbit around the sun where it is farthest from the sun.
Comes from greek ap--=away
The -helio part of each of these specifies that the object is orbiting around the sun. There are other words for orbiting different things.

What is the difference of an aphelion and a perhelion?
Aphelion and perihelion refer to the points in a planet's orbit around the Sun. Aphelion is the point at which the planet is farthest from the Sun, while perihelion is the point where it is closest. These terms are derived from Greek, with "apo" meaning away and "peri" meaning near. The distance between these two points can affect a planet's orbital speed and seasonal variations.
What is the distance in Au between the sun and mercury which is km from the sun?
At its furthest (aphelion) 0.467 AU and at its nearest (perihelion) 0.307 AU.
Does the aphelion and the perihelion happen on the same days every year?
No, the aphelion (farthest point from the Sun) and perihelion (closest point to the Sun) do not happen on the same days every year. The Earth's orbit around the Sun is elliptical, so the dates of aphelion and perihelion shift slightly from year to year.
What is the term for when a planet is at the point of its orbit nearest the sun?
The closest point to the Sun in a planet's orbit is called perihelion. The furthest point is called aphelion. Phil
What is the name of the point on Earth's orbit when Earth is closet to the sun?
The point on Earth's orbit when it is closest to the sun is called perihelion. At perihelion, Earth is approximately 147 million kilometers (91 million miles) away from the sun, compared to its farthest point, aphelion.
Is Pluto perihelion or aphelion?
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.
Is the northern hemisphere summer during aphelion or perihelion?
The Aphelion.
Is 147 000 000 km aphelion or perihelion?
Perihelion.
What is the difference of an aphelion and a perhelion?

How does the distance between Earth and the Sun during aphelion and perihelion affect temperature on our planet?
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.
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 long does it take the earth to move from perihelion to aphelion?
It takes Earth about 182.5 days to move from perihelion (closest point to the sun) to aphelion (farthest point from the sun) in its elliptical orbit.
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.
What is it called when your closest to the sun?
Perihelion - Aphelion is when the Earth is furthest from the Sun.
What is the name of the point in space where an object is closest to the sun?
That is perihelion. Furthest away is aphelion, pronounced ap-helion. For each planet, perihelion and aphelion are at opposite ends of the major axis of the elliptical orbit.
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.
What is the distance in Au between the sun and mercury which is km from the sun?
At its furthest (aphelion) 0.467 AU and at its nearest (perihelion) 0.307 AU.
