Jupiter is the fastest rotating planet.
mercury spins faster.
It requires a VERY SPECIFIC speed for a planet to have an orbit that is exactly circular. Let's assume, for example, that at a certain point in the orbit, the planet's speed is less than this specific speed. In that case, the Sun's attraction will pull the planet closer to the Sun.This, in turn, will make the planet faster; and half an orbit later, it will be faster enough to "escape" from the Sun again. The final result of all this is that the planet will move around the Sun in an elipse.

'definitely, planet A' 'But if you think like this: on planet B an hour has passed in the same amount of time a second has passed on planet A. Then time runs faster on planet B.'
Jupiter rotates faster than any other planet in the solar system, with a day lasting about 9.9 hours.
Mercury.
Mercury.
Earth.
The planet is Jupiter. It rotates in just 10 hours.
A planet travels faster when it is closer to the focus of the ellipse. This is due to Kepler's Second Law, which states that a planet will sweep equal areas in equal times, meaning it moves faster when closer to the focus to cover the same area in the same time period.
All of them.
The length of the planet's year would be affected.
