The sidereal rotation period of Mars - one spin on its axis relative to background stars, is 24.623 hours. This is very similar to the earths sidereal rotation period.
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.
