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.
The sidereal day is the time it takes for a planet to rotate once. For Venus that's about 243 of our Earth days.
Venus has 95 percent carbon dioxide in it's atmospheric composition therefore it has the strongest green house effect in the whole solar system. Venus shows Retrograde rotation. A sidereal year on Venus is shorter than a sidereal day on Venus. Venus's rotation is slowest in the whole solar system.
That planet is Venus. The rotation period of Venus is 243 Earth days. That's called a "sidereal day". On Earth the sidereal day is about 23 hours and 56 minutes. There is also the "solar day", based on the position of the Sun in the sky. On Earth, that's exactly 24 hours. On Venus the solar day is about 117 Earth days in length. As you can see, there is a huge difference in the lengths of the two days on Venus. That's because Venus rotates very slowly.
Neptune's sidereal period or true orbital period. 60,190.03[5] days 164.79 years
224.701 days is its sidereal period
Venus. The "day" (rotation period or sidereal day) is longer than the year! Venus Sidereal day: 243 Earth days. Venus Year: 224.7 Earth days.
The closest is Venus with a sidereal period of 243 days

The sidereal day is the time it takes for a planet to rotate once. For Venus that's about 243 of our Earth days.
Solar day (24 hours for the Earth): about 116.75 Earth days. Sidereal day (rotation period, about 23 hours and 56 minutes for the Earth): about 243 Earth days. Year: about 224.7 Earth days.
Venus has a revolution period that's equal to 224.7 Earth days.
The sidereal rotation period is 9.925 hours
Venus has 95 percent carbon dioxide in it's atmospheric composition therefore it has the strongest green house effect in the whole solar system. Venus shows Retrograde rotation. A sidereal year on Venus is shorter than a sidereal day on Venus. Venus's rotation is slowest in the whole solar system.
243 Earth days is the rotation period of Venus. That's its "sidereal day" length. The other main definition of a "day" is called a "solar day". For Venus that's only about 117 Earth days in length.
