revolution = year
planets revolve around the sun, and rotate on an axis.
hence, shortest revolution is Mercury with 88hrs.
Someone already asked this question (many times), and the answer is Jupiter. That has a day equivalent to about 9.84 Earth hours.
By: 12year old.
Jupiter has the shortest "day" (period of rotation) of about 9h, 55m, 50s.
However, Mercury had the shortest "year" (revolutionaround the Sun) of about 87.97 Earth days.

What inner planet has the shortest year
Of the four inner planets (Mercury, Venus, Earth, and Mars), Earth has the shortest day at 23 hours and 56 minutes sidereal rotation period. That's the "sidereal day". The day that lasts exactly 24 hours is called the "solar day". For both "days", Earth has the shortest day.
Mercury, at about 88 Earth days.
The shortest planetary "day" (period of rotation) is that of the largest planet, Jupiter.With an equatorial rotation speed of over 12.6 km/sec (28,000 mph), Jupiter spins once on its axis every 9.925 Earth hours. (about 9 hours, 55 1/2 minutes)
Jupiter is the planet with the shortest rotation time. It rotates once every 9 hours and 50 minutes.Jupiter in the planet with the shortest rotation time, with a day approximately 12 hours long.
What inner planet has the shortest year
The inner planet with the shortest period of revolution is Mercury, which orbits the sun once every 88 Earth days.
It would have to be Earth, since it is the only inner planet with oceans.
Mercury has the shortest year. One year on Mercury is 88 Earth days.

Jupiter in the planet with the shortest rotation time, with a day approximately 12 hours long.
Mercury, whose year is about 88 Earth days.
Jupiter has the shortest "day" of any planet in the solar system.
Mercury has the shortest year. One year on Mercury is 88 Earth days.
Mercury has the shortest year of all the inner planets, lasting only about 88 Earth days. This is due to its close proximity to the Sun, which results in faster orbits around it compared to other planets.
In our solar system, no planet spins that fast - the planet with the shortest day (or rotational period) would be Jupiter - but it is just under 10 hours.
Jupiter has the shortest rotational (spin) period, about 9 hours, 55 minutes, 30 seconds.
