∙ 11y agoThe answer is NOT Venus. Venus spins once in about 243 Earth days.
That's called a "sidereal day".
Also, rather confusingly, a "day" can mean just the daylight hours from
"sunrise to sunset".
Finally, there's the "solar day". That's based on the apparent path of the Sun across the sky. That's the thing that's exactly 24 hours on Earth.
The important thing, for this question, is the length of the "solar day". That's roughly "sunrise to sunrise". That day depends not just on the rotation, but also on the orbital motion of a planet.
Venus has a "retrograde" spin, and the result is to produce a typical sunrise to sunset time of just less than 60 days, with a
solar day of about 117 Earth days.
The planet with the longest "solar day" is Mercury, with a solar day of about 176 Earth days. So it's Mercury that has the longest periods of daytime and night. So the answer is Mercury.

∙ 11y agoThe planet is Mercury. The definition of "day" that is important here is the "solar day".
"Sunrise to sunrise" is a rough definition of the solar day. Mercury has the
longest solar day. It's much longer than the Venus solar day, even though
Venus takes much longer to rotate than Mercury.

The longest day and longest night of Alaska is what?
Quote from a related question: "Alaska has the longest day of the year in the U.S. No sunset for 82 days in summer. Alaska also has the longest night with no sunrise for 67 days in winter"
On which planet would the time between sunrise and sunset be the shortest?
Since every planet has some degree of tilt between its axis of rotation and its orbital plane, every planet has latitudes along which sunset is immediately after sunrise around the days of that planet's solstices.
Which planet has the longest cycle of day and night of the terrestrial planets?
Mercury. It has the longest cycle of ALL the planets, not just terrestrial.
What planet has the second shortest day?
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.
Which planet is longest planet?
Jupiter is the largest with the largest diameter.
Which planet has the longest day sunrise to sunrise?
Venus has the longest sidereal day (period of rotation or spin). This "day" is 243.0185 Earth days long and Venus rotates in the opposite direction of Earth. This day on Venus is actually longer than its "year". It takes more time for the planet to turn one time on its axis than it takes to go around the Sun. A "year" on Venus takes only 224.7 Earth days.However, the longest solar day occurs on Mercury, which completes its slow spin about once every 59 Earth days but also circles the Sun in just 88 Earth days. This tidally-locked combination leads to a solar day (roughly sunrise to sunrise) of 176 Earth days, twice as long as the "year".On Venus, because it rotates clockwise but orbits counter-clockwise, the effect is to make a solar day ("daytime" is brighter, but there's no sunrise through the clouds) about 116.75 Earth days.Minor comment: The actual question may be asking something different, but that's not clear.
Which outer planet has the longest day?
That is Uranus.
During the daytime when does the sun cast the longest shadow?
As can be observed on any sunny day, the shadows are longest at sunrise and at sunset.
At what time of day will the sun cast the longest shadow?
The sun casts the longest shadows immediately after sunrise and immediately before sunset.
Which time of the day would a trees shadow be the longest?
Just after sunrise, or just before sunset.
The longest day and longest night of Alaska is what?
Quote from a related question: "Alaska has the longest day of the year in the U.S. No sunset for 82 days in summer. Alaska also has the longest night with no sunrise for 67 days in winter"
Which planet has a double sunrise?
Mercury has a double sunrise.
Which planet has the longest cycle of day and night?
The planet is Mercury. (Some people think it is Venus, but it is Mercury.)
On which planet would the time between sunrise and sunset be the shortest?
Since every planet has some degree of tilt between its axis of rotation and its orbital plane, every planet has latitudes along which sunset is immediately after sunrise around the days of that planet's solstices.
Which planet has the longest cycle of day and night of the terrestrial planets?
Mercury. It has the longest cycle of ALL the planets, not just terrestrial.
When the shadow is longest in time?
when its its sunrise and evening.
What is the longest day of the year and when does it occur?
The longest day of the year in the northern hemisphere is during summer solstice. Th longest day in the year for the southern hemisphere is during winter solstice.
