The approximate day lengths (with "day" defined here as the rotation period of a planet) of the planets in the solar system are:
Note that the number for Uranus is its rotation period BUT Uranus spins "on its side". Thus the time it takes for sunlight to illuminate all parts of the planet depends on its orbital period round the Sun, which is 84 years or 735840 hours.
Jupiter: 9 hr, 55.55 min.
Saturn: 10 hr, 32.6 min.
Neptune: 16 hr, 6.6 min.
Uranus: 17 hr, 14.4 min.
Earth: 24 hr.
Mars: 24 hr, 39.6 min.
Venus: About 116.75 Earth days.
Mercury: About 176 Earth days.
These numbers are for the "solar day".
If you use the "sidereal day" for your definition of "day"
then Venus has a longer day than Mercury.
Jupiter, Saturn, Neptune, Uranus, Earth, Mars, Venus, Mercury.
That's for the "solar day".
If you mean "sidereal day", the order is the same except for the last two,
which are reversed, with Venus having the longest day.
Mercury or Venus is longest (depending on the definition of "day" used) and Jupiter is shortest.
Shortest : Jupiter.
Longest : Mercury or Venus, depending on which definition of "day" you use.
(The year is proportional to the distance to the power 1.5) In our solar system, Mercury has the shortest year. Neptune has the longest.
well think about it the planets closer to the sun have the fastest orbit so knowing that the planets are already in order from shortest to longest orbit.
Mercury has the shortest year. One year on Mercury is 88 Earth days.
Mercury has a shortest year of the inner planets - it orbits the sun once every 87.969 Earth days.
The real "planet" with the longest year is Neptune It takes 165 Earth Years. Mercury has the shortest year. It is closest to the Sun and therefore the Suns gravity acts upon it with more strength
(The year is proportional to the distance to the power 1.5) In our solar system, Mercury has the shortest year. Neptune has the longest.

Neptune has the longest year( Pluto would be but it isn't a planet) Mercury has the shortest year(1 year=88 earth days)
the longest
No, it takes the shortest.

Yes. Longest day of the year in one hemisphere, and shortest day of the year in the other hemisphere. So our summer solstice on June 21 is the longest day in Europe or America, but the shortest day for the Australians.
Mercury has the shortest year. One year on Mercury is 88 Earth days.
Longest - Winter Solstice - December 21 Shortest - Summer Solstice - June 21
No, the shortest.
