The sidereal rotation period is 9.925 hours
The nearest is Jupiter with a Sidereal rotation period of 9.925 hours
One day on Jupiter is a little under 10 hours
1.025 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.

The "Solar day" on Venus. Or, the "Sidereal day" on Mercury.
No. Jupiter rotates very fast, and a "day" on Jupiter is a little under 10 hours long.
A solar day is 24 hours whereas a sidereal day is 23 hours and 56 minutes
A solar day is 24 hours whereas a sidereal day is 23 hours and 56 minutes
It rotates very slow. One full rotation on Venus is 243 Earth days. However, the time from sunrise to sunrise, as apparent to an observer on the surface, is 116.75 earth days. The former is what is referred to as the sidereal day, and the latter the solar day.
