The aphelionis the point in the orbit of a planet or comet where it is farthest from the Sun. The Earth reaches its aphelion when the Northern Hemisphere is experiencing summer. The point in orbit where a planet or comet is nearest to the sun is called the perihelion. The word aphelionderives from the Greekwords, apomeaning away, off, apart and Helios(the Greek god of the sun). Earth's aphelion usually occurs sometime around July 4.

Aphelion is the point in a planet's orbit when it is farthest from the sun. This occurs because planetary orbits are elliptical rather than perfectly circular. It is the opposite of perihelion, which is when a planet is closest to the sun.
The Earth passes the point in its orbit where it is farthest from the Sun, called "aphelion",
some time during the first few days of July each year.
In 2010, it was around 6 AM ET on July 6.
In 2011, it will be around 10 AM ET on July 4.
The meaning of the term 'aphelion' in astronomy is the point in a planets orbit when it is at it's furthest point from the star it is orbiting. The Earth has an aphelion point when it is orbiting the sun.
The Earth's aphelion is when it reaches it point in orbit farthest from the sun. An example sentence is: She thinks she feels it when the Earth reaches it's aphelion.
It means when it is farthest from the Sun in its orbit. In the case of Mars, that would be at a distance of about 1.67 AU.
The Earth is at aphelion when it is at the furthest distance from the Sun.
The distance at this point is about: 152,098,232 km or 94, 509,459.8 miles
It is the moment in earth's orbit when it is farthest from the sun. This happens around July 4 or so.
A planet is slowest when it is farthest from the Sun in its elliptical orbit, at its aphelion point.
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.
A planet's farthest point from the sun in its orbit is called aphelion. This is when the planet is at its greatest distance from the sun.
Aphelion, when Earth is farthest from the Sun, occurs around July 4th. Perihelion, when Earth is closest to the Sun, usually happens around January 3rd.
