Since planets typically orbit their stars in elipses, there is a point in which it is closest, and another point in which it is farthest, from the star. The planet perihelion is when the planet is closest to the star it is orbiting.
That is the most basic explanation. =)
The closest point to the Sun in a planet's orbit is called perihelion. The furthest point is called aphelion. Phil
A planet's closest approach to the sun is called perihelion. This is when the planet is at its nearest point to the sun in its elliptical orbit.

Neptune is located at aphelion in its orbit. It is the furthest from the Sun while it is in its orbit.
An anomaly refers to the position of a planet or satellite that is defined by its angular distance from its last perihelion. It is considered an irregularity in the motion of a planet or satellite.
This is the Perihelion.

Perihelion is the point in a planet's orbit when it is nearest to the sun. Apehelion is when it's furthest from the sun. We would not be coldest at perihelion.
The perihelion is the closest point to the Sun in the orbit of a planet.It is different for each planet based on the elliptical variation, but will always occur at the same point in each orbit.
