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.
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.
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 speed of a planet revolving around the Sun is slowest at the aphelion, which is the point in its orbit farthest from the Sun.
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.
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.
