Uranus has the longest day of any planet in the solar system, with a rotation period of about 17 hours and 14 minutes.
The planet is Mercury. (Some people think it is Venus, but it is Mercury.)
Yes, Billions of people do each day. The Earth is a planet :-)
Mercury has the longest "solar "or apparent day. Mercury takes 88 Earth days to go around the Sun, so its year is 88 Earth days. It spins very slowly on its axis though, once every 58.6 Earth days days relative to background stars. A solar (apparent) day on Mercury takes 176 Earth days, because of this slow spin relative to the time taken to orbit.The spin of Venus relative to the background stars is slower, taking 243 Earth days to spin once on its axis. But since its spin is retrograde (clockwise as viewed from above the north pole) and in the opposite direction of orbit around the sun, the apparent solar day is less, at 116.75 days.So, Mercury has the longest "Solar day". However Venus has the longest "sidereal day", because that's defined as the rotation period.
Jupiter is the fastest rotating planet int he solar system.

The length of a day on a planet would determine how long you sleep. Venus has the longest day in our solar system, lasting about 243 Earth days. So, if you were to live on Venus, you would have a much longer day to sleep through than on other planets.
No planet in our solar system has days longer than one Earth year. Venus has the longest day -- it's 243 Earth days.
Jupiter has the shortest "day" of any planet in the solar system.
Jupiter is the biggest in our Solar System. Outside, the object is changing almost every day.
There are no planets in our solar system with a rotational period of 318 days. The longest is Venus, with a rotational period of 243 days.
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 daysIf 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.
A "sol", or solar day on Mars, is only about 40 minutes longer than a solar day on Earth. This is by far the closest to being the same as Earth's of any planet in the solar system.
Jupiter rotates faster than any other planet in the solar system, with a day lasting about 9.9 hours.
August 24th 2006. It was a Thursday.
Planet with an atmosphere, Venus. Planet without an atmosphere, Mercury (on the day side).
