Neptune is located at aphelion in its orbit. It is the furthest from the Sun while it is in its orbit.
perihelion
The earth is moving fastest in its orbit at the moment of perihelion, when it is closest to the sun. the happens around January 3.
8minutes 27seconds when the Earth is at aphelion, early in July. 8minutes 11seconds when the Earth is at perihelion, early in January.
No. Hale-Bopp is a comet. Comets are much smaller than planets, and travel in very eccentric orbits. This means that they come fairly close to the Sun at perihelion, and then retreat to great distances.
The speed of planets will vary as they travel at different speeds. Mercury is the fastest planet while Pluto is the slowest. The speed of the planets is influenced by how close they are to the sun.
Aphelion (Furthest distance) 69,816,900 km - 43382210 miles - 0.466697AU Perihelion (Closest Distance) 46,001,200 km - 28583820 miles - 0.307499 AU Semi Major Axis (Mean) 57,909,100 km - 35983046 miles - 0.387098 AU

Yes. The planets travel fastest at perihelion, the closest point to the sun in the orbit, and slowest at aphelion, the farthest point.
This is when the planet is at its closest point to the sun on its orbit around it. If its distance carts by enough it will experience higher temperatures at the perihelion. It will also be orbiting at its highest speed at this point.

In elliptical orbits, all bodies travel faster when nearest the "primary"; in this case, the Sun. Since the Earth's orbit isn't very eccentric (meaning that it is almost but not quite circular) the difference between perihelion velocity and aphelion velocity isn't very great.
The Earth travels around the sun in an orbit that is in an elliptical (oval) shape. The sun is not in the center of the oval, but nearer to one end. The point in Earth's orbit when it is closest to the sun is called the perihelion, and that is also the point when the Earth is traveling fastest in its orbit. Where it is furthest from the sun (aphelion) is where it is traveling slowest.
Mercury travels around the sun faster than any other planet (88 Earth days) because it is the closest planet to the sun.
faster nearer to the sun, the sun has more pull to move it faster
The planet always moved very fast. But it's fastest velocity would be attained at it's nearest approach to the sun.
No. Hale-Bopp is a comet. Comets are much smaller than planets, and travel in very eccentric orbits. This means that they come fairly close to the Sun at perihelion, and then retreat to great distances.
Sedna, a "dwarf planet" far beyond the orbit of Neptune, has a highly elliptical orbit with a perihelion of 76AU, or about 631 light-minutes from the Sun, and an aphelion of 975 AU, or about 8,093 light-minutes or 5.6 light-DAYS.
When at perihelion ie nearest the sun.
