A planet in an elliptical (oval) orbit will move faster as it gets to its closest point to its sun, and slow down as it reaches its furthest point. A planet with a truly circular orbit will have a constant speed.
Near the Sun the force of gravity is very strong so the planet has more energy which means it has to move faster.
That would be Mercury. Venus also has no moons, but does not move as fast as Mercury.
Storms on Jupiter can move at incredibly fast speeds, with some reaching speeds of up to 400 miles per hour (644 kilometers per hour). These storms can cover large distances quickly due to the planet's intense weather patterns and fast rotation.
The Sun doesn't move fast, but if you mean which planet moves fast around the sun then it would be Mercury, because it is closer.
I think they all do in this solar system, but maybe someplace with two suns has a planet without night. On a binary star system when the planet move between the stars in part of it's year there will be no night or only daylight.
