Mercury has the 2nd longest "sidereal day" with a sidereal rotation period of 58.646 Earth days. The longest "sidereal day" day is Venus, with a sidereal rotation period of 243.018 Earth days
If you use the "solar day" as your definition of "day", the order is reversed. Mercury then has the longest day and Venus has the second longest day.
Jupiter has the shortest "day" of any planet in the solar system.
Mercury is the shortest and Neptune is the longest
To arrange time divisions from longest to shortest, the correct order is: year, month, week, day, hour, minute, second. A year encompasses the longest duration, followed by a month, then a week, and so on, with a second being the shortest measurement in this sequence.

Jupiter in the planet with the shortest rotation time, with a day approximately 12 hours long.
Jupiter has the shortest "day" of any planet in the solar system.
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.
What inner planet has the shortest year
The planet Mercury has the second shortest year in our solar system, with a year lasting approximately 88 Earth days. This is because Mercury orbits the Sun much faster than Earth due to its close proximity to the Sun.
neptune is the furthest actual planet from the sun, approx 3 miles per second. although, pluto (now a dwarf planet) is approx 2.5 miles per second.
That depends where you are on the planet. the length of day is shorter the further away from the equator you are.
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.
