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.
Yes. The planets travel fastest at perihelion, the closest point to the sun in the orbit, and slowest at aphelion, the farthest point.
If you're referring to the orbit of the Earth around the Sun, the closest point is called the perihelion and it usually comes between the 2nd and 4th of January each year.

The planets orbit the Sun. The Sun is at the center of our solar system and does not move.

Planets orbit stars in elipses, or elliptical orbits, which means their orbit around the star is an oval shape, as opposed to a circle. That means that at one point they will be closest to the star, and at another point they will be the farthest. Perihelion is when the planet is closest to the star, so the perihelion date is the date of which the planet is closest to the star.
Closest point is called the perihelion; furthest from sun is aphelion.
This is the Perihelion.
All the planets orbit in a perfect circle, so they always stay the same distance from the sun, except Pluto, which is why it is now a "Dwarf Planet".
740,573,600 km at its closest, and 816,520,800 km at its furthest point - like most of the planets, it follows an elliptical orbit.
