It means the point where a planet, or other object, is farthest away from the Sun in its orbit.
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.
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.
It comes from Greek apo- which means "away from". Thus "aphelion" is the point in a body's orbit when it is farthest away from the Sun (helios) and "apogee' is the point where a body orbiting the Earth is farthest from the Earth (geos).
Aphelion
When it is farthest from the Sun. This point is known as aphelion. *Aphelion = Furthest point from the Sun.
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).
Aphelion distance can be calculated using Kepler's laws of planetary motion. For an elliptical orbit, the aphelion distance (the farthest point from the Sun) is given by the formula ( r_a = a(1 + e) ), where ( r_a ) is the aphelion distance, ( a ) is the semi-major axis of the orbit, and ( e ) is the eccentricity of the orbit. By determining the semi-major axis and eccentricity of the celestial body’s orbit, you can plug these values into the formula to find the aphelion distance.
The sun. Aphelion is the point in Earth's orbit where it is farthest from the sun.
In general the farthest point in a satellite's orbit from its focus is its apoapsis. If the focus is the Sun or Earth however then you would say the satellite's farthest point is its aphelion and apogee, respectively.
The northern hemisphere does not experience winter when the Earth is farthest from the sun.The cause of the seasons is the Earth's axial tilt, which is independent of the apsides of Earth's orbit, known as aphelion and perihelion.When Earth is farthest from the sun, it is at aphelion. Aphelion currently occurs in July, which is the Northern Hemisphere's summer.
